Yes, I think you're right. My game hung (completely froze the iPod Touch) after updating, and I think that might've been where it happened. I had to cold start to get my device back. It froze just after the "lawn carpet" rolling sequence almost finished, when the zombie head pops up at the end, but before "tap to start" appeared. When I came back from that cold boot and restarted the game, it worked fine but my coins were gone/reset to minimal levels. It's not a big deal for me, as I have a full zen garden, so I'll just blow through some chocolate and farm until I get what I need. Everything else in the game seems to be fine.
