Sim doesn't interact with others and instead starts dancing/twitching

Could you please provide the following information

-  Are you using mods/cc in your game ? Please remove them and test without them if you do.

 I dont use any mods or cc. Full vanilla game

Thank you for confirming. I merged your post with the main thread then.

Please provide your save game to EA: [INFORMATION] How to Send User Files to The Sims 4 Team | EA Forums - 5048472 

I have the same problem. Removing cc and mods doesn’t seem to work. I tried other things such as deleting localthumbcache.package and disabling my packs and the problem persists. None of my save files are playable.

i was able to fix this but i had to uninstall the game and redownload it onto my external hard drive and it worked fine after. im not sure what else can be done to fix it though i know uninstalling and redownloading is tedious. if you use mods you can keep them all just move your mods folder out of the sims directory before uninstalling and once reinstalled replace the new mod folder with the one you kept from the previous install.

I tried uninstalling and redownloading the game, and it finally worked! Just make sure you move your mods and saves folders to desktop before uninstalling.
