Exactly what it says on the tin. Avery Sonshal, the shopkeep on the ground floor of Felogyr's Fireworks, will crash my game on his turn in combat, every time.

I'm not sure what the hell he is doing, but he just stands there for several seconds, uses the dash action, and then the game crashes out. I've let the crash report put in a notice, as well as posting here. Pretty sure this is a known issue, as I recall hearing something about Felogyr's Fireworks being bad and causing crashes a while back.
