I bought the Apple Dot tiles for my floor, covered the whole floor with them, but when I opened the game the next time the tiles had disappeared
I bought some more for my recently expanded area, and when I tried to place them, the -3 appeared (ie the money went), but no tiles were placed.
Then when I logged back in the next time the tiles appeared only in the new expansion, but not the rest of the floor
Any idea what's happening??
