Hey everyone!

I'm completely devastated right now! My House, which I have been working on for AGES! Seems to be broken. Sad I really need help fixing this, because I can NOT lose this house!

What happens is:

when I load the lot, the screen stays black for about 2 minutes, except for the menu, I figure my computer takes a while to load the graphics, then it appears, but when I try to zoom in/move the camera it freezes, or the camera jerks back and forth (I don't know how to explain it better) I can still select different tools/etc but shortly after the game crashes. This only happens on this lot, other lots are fine! I've already deleted tons of custom downloads, but I never had problems with the game being laggy before, I have quite a lot of unused space and RAM left.

What is the problem and how can I fix it?

Thanks a lot, I appreciate every reply <3
