Here is a list of known issues in the game:

I get a, "No Free Space" message when I try to pop a bubble, even though I have free space: Try moving the bubble close to the free space.

"Cannot wake Villagers, no one is sleeping" but there are Villagers sleeping: We hope to have this fixed in a future release.  In the meantime, you can try a clean reinstallation of the game (clear the store cache), but make sure your account is secured, first.

I can't open my Event Chest:  This has been a problem for a while, but we are working on it!  It may be fixed in the near future.

The game keeps crashing:  We're investigating the current crash reports.  If you experience crashes when playing the game, please send us a support ticket.
