outdated/mod

Hi. I am playing on an iMac and every time I click on my sims relationships, it freezes and plays music and won't let me do anything. I keep getting a last clean exception which I believe I have outdated/broken mod. How do I find out which mod it is? Here is the last clean exception text file. 

Hey @oreosimmer01,

I've moved your post to a more relevant board than EA General Questions.

Hey @oreosimmer01,

I've moved your post to a more relevant board than EA General Questions.

Hi. So I keep getting last clean exceptions, last ui exceptions, and just last exception texts. I have one of them here but every time I load up my game it gets stuck on the loading screen. I do have mods and cc in my game and when I remove them it loads perfectly. Is there any way that I can tell which mod is broken/outdated? Thanks. 

@oreosimmer01 Hello!  I'm no expert at reading the exceptions but in the last LCE you posted, it looks like most if not all the errors are coming from the basemental mod.  Try taking that one out and testing the game.  You might need to check for an updated version.  There may be other mods or CC causing issues though.  It looks like you have quite a bit so I suggest testing your mods/CC a little bit at a time and delete the localthumbcache.package file located in the Documents / Electronic Arts / The Sims 4 folder before opening the game for testing. You probably want to create a new game for testing so you don't make any changes in your current save until you find the one(s) causing the problem. If you do have a lot of mods/CC, the 50/50 method works best.

1. Divide your mods/CC in half (maybe make a folder on your desktop to hold the half you're taking out).

2. Delete the localthumbcache.package file again, before opening the game with the half you're testing, 

3. If the game works with that half, test with the other half. (Again, delete that cache file before opening)

4. Once you know which half is causing the issue, divide those in half and test again (delete the cache file again).

5. Repeat the process until you find the culprit.

Could you help my problems? First is that l can not change the color of skin, eyes, hair, or eyebrows, on the sim. I change everything else. My second problem is that every time l click on a lot to start or continue on it, it brings me back to the world gallery and usually says an error happened and to relaunch the game. This was after l updated it. I tried going through my custom mods, rebooting my computer, starting new sims 4 game, and relaunching games a thousand times. Btw l'm on pc. Can you help?
