So, this phenomenon has happened twice, on two different save games. It happens after playing two or three times (after maybe spending 6 hours total re-modeling lots and whatnot).
And here it is:

A majority of the lots have become gaping holes in the terrain. It's not the floating terrain problem other people are having, because the terrain is still in place, and the lots are just GONE. The last time I saved, everything was normal. Then I reload the game and this happens, every time. I'm patched to version 1.7.
Help?
