Re: Opens build mode by itself
@annette_27399 Hello! My, that's a weird one. Since you removed your mods, try also deleting the localthumbcache.package which is in the Documents / Electronic Arts / The Sims 4 folder. You also want to repair the game after that; exit the game, right click on the game in Origin and select Repair. Depending on the number of packs you have, that might take a while. After the repair is complete for all packs, open the game and see if it's working. If so, you can try adding your mods back in a little bit at a time to test them in your game and see which one is causing the issue. Also, check the creators' sites and make sure you have the most recent and updated versions. Outdated mods can cause many various issues.
If you're still seeing the issue without mods, after clearing the cache and repairing the game, then come back and let us know.
