Sims 4 crashes when trying to play/enter Build Mode for lots in Willow Creek

My girlfriend and I have our own games (I didn't know clicking the Play icon was starting a new game, and that you had to load a game to continue), and the same lots on hers (She hasn't played in months) are able to be edited and such. But I still can't do anything with them on my own game. I really don't know why that is. Her game allows Build Mode and to play Sims living on those lots.

If it's just the one save game, something might be corrupted.

Did you try exporting your family to the gallery/library and start a new game with it ?

Well, I'm willing to try that, except a lot of my Sims and houses are modded, and it won't save anything that's been modded to my library.

It does. You just have to be online for them to show and turn on cc in under advanced filter
