A bit of background: So I have been having this Sims 4 bug for a while now, and it has been making me dislike playing Sims since I can't have more than one saved game in my world. If I make a new household, I can only access my old one one more time before the game deletes the family and the lot will get reset back to the basic lot (which sucks since that means that my work was for nothing). But I discovered that this glitch doesn't only affect ONE save, it affects every single save in my game. Newcrest plots get wiped, if I altered Sims from other worlds then they get reset back to their base game models, and I'm stuck with my one family.
So, I did some research. I learned from this website (Carl's Sims 4 guide) that if you delete your cache folder, it could help. When I went into my EA folder, I found out that my cache folder has been empty this entire time. The onlinecache one was also empty, as well as cachestr. I removed some random files that I saw pop up in your guide, but it didn't solve the problem.
Please help--I'm an avid Sims fan and I'm starting to dislike the game because of how I can't make new saves or even design houses. The a few of the purposes of the game are basically gone, since now I'm stuck with only one save file and whatever work I do in that save before everything gets wiped from a new household.
