Just installed the game and all it's expansion and stuff packs on an excellent new computer.
I come across an issue where, after successfully saving this file multiple times, saving continues on forever. I give it time, thinking it's nothing out of the ordinary, but after an hour the game is still saving.
I go into the saves folder in The Sims 3 folder, find that my original file that should be under "saves" is gone. This issue seems to have corrupted the file, causing the game to delete it!
I decide to investigate, so I make my game again and do everything as I had done before, it saves fine repeatedly, and then suddenly I have that same issue again. I notice it occurred after I had accessed build/buy mode to place some stuff for my sim.
So I re-make a file and go through, adding each object I added before to see what exactly triggers the eternal-saving issue. After placing a door from Ambitions (it's called "A simple door" or something like that, it's the cheapest door in the game), I have the saving issue again. So the problem is with the door. I test it out a few more times, making sure the issue is with the door. It happens again, saving never ends after placing that door. I then try saving after placing a different kind of door, and the issue happens again. So the issue appears after trying to place any door at all.
Again, each time this eternal-saving thing happens, the file I am trying to save gets deleted within the saves folder.
I have no idea how to fix this, I've tried factory reset and that hasn't fixed it. This is a bizarre issue that renders the game unplayable because I have to place doors at some point! I have lots of Nraas mods and the Ultimate Careers mod by Zerbu, none of them conflict, and I have lots of Store Content and one third party skin. I have tried to run the game without CC and the issue persists.
Any ideas what I could do to fix this?
