Can't move buildings anymore.

After the last update, the buildings don't want to move to the different patches of land. What gives?
What do you mean? What happens when you try to move a building?
Do you get an error message or something?
No error message

I cannot move my strategy building from the one side of the STD to the other. It wont let me do it by either pressing on the empty space - or dragging it across. Its like there is a field that cannot be crossed that goes diagonally across the screen.

Saying that, its only affecting some building type for me.
Did you buy a vacant lot first? Maybe you cannot swap spots... you have to do 3 moves to complete
swapping places of two buildings using a vacant lot to help bldg1 vacate for bldg2 to move in.
