My assumption is the huge amount of on hit effects, converted really slowly (I was playing with 1 fps at some point) to light/dark via fixedart amulet, as well as the interactions of demonologist talents. But then again, I have no idea.
The bug presented itself when I entered a mini vault with exactly 30 Cold Drake Hatchlings and used my only AoE of 1 radius, Demonic Madness, which causes other simultaneous AoEs of radius 2 via the Overkill sustain. BANG. Everything went white, I saw (Dark)God, even the Lua error screen was white. Well maybe I didn't see DG but the rest remains the truth. A few moments/turns/keysmashing later it was back to normal. Another turn later I got another Lua error which I was able to read this time around, the one on the log above.
Stunt forwarded me here and that's pretty much the end of my testimony. Have a nice day
edit: After posting the bug, I tabbed back in to be on my merry way, assuming all would be fine with the low number of hatchlings remaining, took 2 steps, and bang, crashed. the log : http://pastebin.com/werNQbCV
