instance crash - vaal caster (surgeon spammer mob)

/bug executed but didn't copy ID to clipboard

game froze, looked kinda like a DC but not quite. happened in vaal factory with vaal caster SFX on loop. this happened b4 to me in Stone Citadel (same SFX) but didn't lose the map. in Stone Citadel I alt+f4, this time i let it cook, and it cooked my map

still happening, happened in Ravine map, same mob, same sfx on loop, map also lost (only times i lost maps is due to this)

*also all drops from that map poofed
