I just witnessed this same crash happen to Shinkaigan.

This occurred post-patch. I was playing as Skaarf (NA server) on my iPad 3 and after about 20 mins into the game everything froze for about 5 seconds. But the game didn't crash it booted me to the main menu. It didn't try to rejoin my game. It didn't give me a penalty for leaving either. I'm not sure if it happened to just me or everyone in my game. I killed the game and relaunched and it still didn't auto-join my current game. Anyone else experience this at all?
