broken lot in Newcrest??

The problem that I'm having most specifically is lots. Not necessarily any builds. As I said it doesn't matter what build I use whether from my personal library or gallery the problem is lots. There are some faulty builds but I typically stay away from them and simmers let each other know in the comments if that build will crash the game or cause lag. I could use base game builds with minimum clutter and still have this problem. I even bulldozed a build and left the lot empty and it still continued to load when I tried to return to manage worlds. I'm sure the problem isn't builds it's the lots.
