Troubleshooting | MC Command Center

Last Exception Tips:

A LastException.txt can be generated when your game is loading. If this happens, you will not see MCCC in the game even if you have it installed correctly. You can tell this happened by going to your Sims 4 folder and you will see a LastExceptions.txt file that is generated during game loading. This VERY OFTEN has to do with other mods/cc that are out-of-date and are preventing the rest of the mods from loading due to their errors. The instructions below for dealing with LastExceptions applies in this case as well.
As of MCCC 3.5.0, a notification is shown when LastExceptions occur. These almost always happen as a result of bad or out-of-date mods or CC. They are rarely caused by MCCC itself. Note that I did include CC with that! Some of EA’s patches breaks custom objects or clothing items as well and sometimes it can prevent mods from working correctly if they are deployed. These LastExceptions will continue to happen until the mods/cc causing problems are removed or updated.
EG, one of our support team from the Discord server, has compiled a helpful document of ways to work-through possible issues causing Last Exceptions. More details can be read on her post on Patreon here
The best way to verify that the problem is happening due to MCCC and not other mods/cc is to run the game with only MCCC in the mod folder, and it's best to put it in the mods folder itself and not a sub-folder. Remove all other CC and mods into a temporary folder outside the Sims 4 folder. If running the game with only MCCC in the mod folder works with no issues, then the problem is definitely in the other mods or CC that were in use previously. If that’s the case, the 50% method is a popular process used to track-down what CC or mod is causing the problem. You can see how this works here.
MOD CONFLICT DETECTORS WILL NOT HELP FIGURING OUT THESE ISSUES!!! I can’t stress that enough! Mod Conflict Detectors detect when two CC mods are altering the same resource ID. They have nothing to do with determining whether or not a mod or CC are OUT OF DATE and causing exceptions!
Another test that can be done is to remove MCCC and run the game with all other mods/cc but NO MCCC. After running the game that way, check the Sims 4 folders for new LastExceptions. You’ll find that a new one gets generated there regardless of whether MCCC is in the game. MCCC only notifies the user that LE’s are being generated. It doesn’t generate LE’s. The Sims 4 code does that. MCCC just monitors the Sims 4 logging and notifies the user if an exception was logged. That’s all!
On the Discord server, which I have links to at the bottom of my website and on the main page, we have a #error_support channel where there are often people that are willing to take a look at LastExceptions.txt files and give suggestions on what may be causing the issue. Sometimes, there is nothing anyone can do, though, as the errors are just too generic to pinpoint which of thousands of mods/cc can be causing them. That’s when it just comes-down to the specific person’s installed mods and cc and they alone can track it down. Using the suggestions above, it is absolutely possible to do so. It just takes the patience (you have to supply) and methodology (several different techniques mentioned above) to do it.

Troubleshooting Tips

You can look in Game Options/Other/Custom Content and the mods should show-up as loaded in the Script Mods section. Make sure you have the checkbox on Game Options/Other checked for allowing script mods. If the modules show-up in the Scripts and Custom Content section, then that means the Sims 4 found the mod files, but it doesn't necessarily mean they are loaded correctly. This confirms the mods are installed correctly only. If the modules don't show-up in the Scripts and Custom Content section, then the first thing to try would be to place all the MCCC mod files in the main mods folder and not in a sub-folder. If that fixes the issue, then the resources.cfg file in the mods folder is bad. It can be deleted and a new, correct config file will be generated. If that still doesn't fix it, then there is likely another installation issue, so referring back to the installation documentation and video would probably be the best step to follow.
If the mod shows-up in the Custom Content section, but doesn’t show-up when clicking on Sims or computers on a lot, then one of the things that is a leading cause of this issue is if you don’t have the right version of the mod for the version of the Sims 4 that you’re playing. When I do a release, I list in the release notes what version it works for. Versions before what I list will often not work correctly with the mod. Versions after that may also not work if EA has released updates after the version that I have listed there. Basically, the rule of thumb is that if you are using the latest version of the Sims 4, which you should be, then you should be using the latest version of my mod as well that will be the one compatible.
As of version 1.13 of Sims 4 (Get Together Expansion), any time EA releases an update, they are forcing the settings of the game to have mods disabled. Ensure that if an update from EA has just been applied that both checkboxes for Mods are enabled: the checkbox for enabling mods and the checkbox for enabling script mods.
When the game starts, a notification message will pop-up with the current version of MC Command Center deployed and all of the modules that are currently included on your game. If this doesn’t display or if all of the modules are not displayed, then there is something wrong so continue looking through the troubleshooting steps. If it does display, then the mod is loaded correctly. Additionally, you should be able to click on a computer in a game lot or on a Sim and see a “MC Command Center” menu.
If the mod is loaded but you can’t tell if it’s working (you haven’t seen pregnancies or move-in notifications), turn on logging by enabling the “Message Logging” setting in MCCC > MCCC Settings > Notification / Console / Menu Settings > Notification Settings > Message Logging. When you run the game and your home lot loads, if you go to your mod folder and open the mc_cmd_center.log file, it should have “Initializing MC Command Center version” at the top of the file. Every night at midnight, alarms will run and this log file will have updates in it telling what happened for that day when the alarm ran.
If the mc_cmd_center.log file doesn’t exist but according to the Game Options/Other/Custom Content window, the script mods are all loaded, then you may have a version problem. You can look at the LastExceptions.txt file in the Sims 4 folder to determine if that’s the case. ALSO, if the MC Command Center mod files are more than 1 sub-folder deep in the mods folder, the Sims 4 game will not load the scripts and run them so you will get no errors and no log files, it just won’t run. For example, “Sims 4\Mods\MCCC” will work and “Sims 4\Mods\ScriptMods\MCCC” will not.
You should verify that your mods folder looks similar to the screenshot included within the “Installation” documentation. The dates and sizes of the modules may be different if the screenshot is older, but the location and names should be similar.
There are some mods that are known to conflict with MC Command Center. This is usually caused by functionality in those mods that is already in MC Command Center so a separate mod is not needed and causes problems. There may be other mods that we aren’t aware of that also break the game but are not incompatible with MCCC.
Keeping your mods folder in-sync with OneDrive can cause permission errors to happen within MCCC since it has to save your settings to the mc_settings.cfg file. If you get an error when you change your settings that says “PermissionError: [Errno 13] Permission denied” and it has a “OneDrive” folder listed in the error, then that’s the cause. Accessing the OneDrive synced folder for writing settings can cause permission errors sometimes so the syncing has to be disabled. Also, the Sims 4 folder for mods should be on a physical drive. Putting that whole folder on a OneDrive server can also cause problems.. Another option would be to use another file syncing service other than OneDrive as it is the one that specifically seems to have this issue.

Known Mod Conflicts (If you use these, you will definitely have problems so don’t be surprised!!):

Autosave for Sims 4 by sachamagne
Neia’s “No More Same Sims Everywhere”
TwistedMexi’s Always Testingcheats mod, but I’m not sure if it works even on its own or not.
ArtURLWWW’s Pregnancy Mega Mod conflicts with MCCC. They are two mods that do the same thing so there will be conflicts. Everything in PMM is already available in MCCC so an additional mod is not needed. Trying to use both will result in MCCC not working.
The “Sticky Clothes” Mod conflicts with my mod as I also have that functionality built-in to MC Command Center automatically.
Cowplant Tweaks from kylebeans doesn’t seem to be supported any longer and can cause issues when in use.
“Woohoo is Exercise” by Candyd is known to conflict with MC Woohoo.
The InTeen mod hasn’t been updated or supported since 2014, I think it was, so it definitely will cause problems all on its own…much less when combined with anything else!

After checking those things, I can help analyze further, but there are basic steps you can take to make it easier to figure-out what is wrong.

A screenshot of your mod folder can be helpful.
A screenshot of your “Game Options/Other/Custom Content” window showing the script mods that are loaded will help.
A copy of your mc_cmd_center.log file can be helpful, depending on the problem. A copy of the LastException.txt file from the Sims 4 folder can be helpful (Note that it is only the LastException.txt that I refer to as there are sometimes LastException files with numbers in them but those are old so less helpful).
Vague comments like “it’s not working”…not so helpful. :)
