Bug 1: Sprite bug.
When Boss spawns, he shows up dead lying on the ground but he still attacks. Me and my guild haven't finished this boss yet. Just a normal sprite error.
Bug 2: Time out bug.
The game freezes when timer runs out and your party auto wipes. Happened to me twice already. The game does not literally freeze. You can still click buttons like End Turn, Auto, and Menu. Tried quitting the game to see if I can "Continue" to redo a fresh run without wasting keys but relogging brought me to Town Menu. I don't know if the keys were used up because it was exactly right after reset time.
