hey! had the same issue, browsed the forums and ended up contacting ea myself. first try this with the mods tho:
1. delete localthumbscache
2. move mods folder to desktop
3. delete everything in it
4. repair game (in ea app next to play game under manage)
5. open and see if new mods folder was created, if not make one yourself or move old one back (made a new one)
6. see if it worked, if not try ea help steps below
the reply from ea help:
1. Delete the localthumbscache.package file in this directory.
2. Go inside the cache folder and delete all files that end in .cache, but do not delete the actual directory (folder)
The .jpg files as well as the .dat that you find in the cache folder are safe to delete. These come from viewing households/lots from the gallery. If you play with the Online Access Feature turned off, or play offline, you may not have anything in this folder.
3. Go back, then to the cachestr folder. Delete all files here, but again do not delete the actual directory.
* It's okay to delete the spotlight.package file.
4. The onlinethumbnailcache folder is safe to delete IF it is present.
extra: always update your cc and mods after an update. for that you have to download all of it again (new versions from the creators, who should update it)
extra 2.0: just dont have mods or cc because I just had the scare of my life trying to fix this (400 hrs play time almost thrown out the window help)
