What were you expecting to happen, and what actually happened
After making a match, new gems fell onto board and 2 possibly overlapped/combined? And froze board. The rest of the game was still active in background, but only the menu button would work.
How often does this happen? When did it begin happening?
Only once thus far.
Steps to make it happen again
Unknown, play game.
