I've noticed that after some play, some buildings hop almost all the way out of the grid square where they were placed. they can be demolished and rebuilt correctly. I do not know what causes this and have not been able to reproduce it, but it happens quite a bit.

all 3 instances of this seen in the screenshots were the "house" city improvement, on the particular map i was playing on, all 3 were located in the same city.
