Would you be interested in collaborating with someone on it?
This is from the daily today:
Early in the game monsters bugged out and they stopped moving. My guess is that an explosion + level up happened at the same time. The only gameplay modifiers at the time were a wildcard (purple + red) and monsters acting slowly.
Cause of death:
I had active teleportation, so during one explosion while teleporting to a new piece, my increased multiplier caused more tiles to be destroyed - including the one I was teleporting to. This one is more of a feature than a bug, but would be a feature which I wouldn't miss :)
