I tried to first play a non-modded, vanilla game. No cc or mod in the folder.
The build my preferred save lives in is a custom build from an online simmer, but it has no mods or CC.
I deleted the build to start fresh, and moved my family into a Maxis-built house. Everything was running smoothly.
After a few successful game plays, I brought back the one cc furniture pack I love into the Mods folder. Incorporated a few items into the Maxis house and seemed to work fine.
Eventually I got too confident and redownloaded the custom build from Summer Plays (https://www.youtube.com/watch?v=NMxi66DyzJc).
Placed the lot. Moved the family. Everything was great.
I slowly started redecorating with the CC pack. Room by room.
Thought I was good.
Then it crashed, randomly.
Should I just forget about my save completely for right now, and try to play the game fresh? I do play with Mods and CC so if for some reason I can't use those things, I would just return the computer. I want to be able to use CC even in a new save.
I'd buy you 1,000 coffees if I could for your help.
