Everytime I exit build and buy mode my game freezes

If you have any mods move the mods folder to the desktop, delete localthumbcache.package file in the game. Delete also all folders with the word "cache" in the name - important!
Fix the game in Origin.
Origin/Library - right-click on TS4 - option "Repair game"
You have to wait until Origin will fix all packs, not only the base game. Turn on the game to create a new, empty mods folder and check if the game is working now properly without mods

I don't work for EA
