bug report!
lets say you turn a tile into multi-block, move it, and you reset it.
everything is fine, tiles are moved to a new position.
and then you Undo back to point before you reset and reset tile again, but the tile does not reset, it instead stays as multi-block until you undo to the point before you turned it into multi-block the first time.
made one level harder to beat than it should've.
