In 2.55 (2.55 Win Alpha 52), I attempted to move tiles from my tile pages from pages 0-251 to somewhere past, so page 300-800. It looks like it moves the tiles correctly. However, the Combos that were assigned to them work, except for the ANIMATED combos. So anything that was animated, did not move.
I meant to update the Subject line to say: [255] - Moving tiles past page 251 messes up Animated Combos.
Update: Also happens on in Alpha 58.
