Saves in weird spot, relationships are missing, game lag

My relationships and friendships are gone, game saves in weird places and game is taking forever to load. Please fix this. I tried to use testingcheats to build my relationships back but it’s not working. People who my sim has build valuable relationships with in the magic realm are completely gone. My other sim is missing her entire relationship and doesn’t even know the guy anymore.  It’s so frustrating. I even click on objects and it takes forever for a menu to pop up or just doesn’t respond at all. Getting off the game for today.
