Sims 2 frozen black/teal lot...?

Question

I built a basement garage and saved the lot and left it. This is the first time this has happened. I can't select the lot, delete it, play on it, etc. It appears black and sometimes teal when you move over it. Any idea as to how to solve this problem would be greatly appreciated. Thanks.

Answer 2
