Problem with rebuilding lots in new world.
I downloaded a world which I want to reconstruct. So, first I made small tour arond the town and I entered some lots to view them. Here I found an issue: several lots didn't open to the bulding mode, they only came closer but there wasn't building tools below, only the families selection. I hope that is understandable. I mean I can't see these few buildings inside, build or buy. I also can't save these lots or delete them- there is only processing screen for very long time and than I need to shut my game through ctrl-shift-del. Why is this happening? Is there a way to solve it? I hope that what I wrote makes sense, sorry for my English. I hope someone can help me to solve this problem. Thank you!
