Re: Accidently updated updated mod whilst sims was open
@Baabydxll This is unlikely to be because Sims was open when you added a mod. Try a vanilla test: Drag the Mods folder to the desktop, delete the file called localthumbcache, open the game to test, and exit without saving. Test on a new save as well as your regular one.
If that works, copy the files (but NOT resource.cfg) out of your old Mods folder into the new one the game has now made and try again. If the problem returns, you can use Broken/Updated Mods to start the process of checking for updated mods, and for mods not listed at AHQ, you can check the modders' own websites for updates. Delete localthumbcache when you update, and keep exiting without saving while you test.
If this doesn't help, please let me know! I can send you to where you can get help with non-mod causes.
