Notes
(0004200) Warmonger (administrator) 2013-12-23 14:51	It could be helpful to tell the details, such as WHICH spell was cast under what confitions.

(0004201) KroArtem (updater) 2013-12-23 14:52	Unfortunately I don't remember, though it's not that hard to reproduce. I'll try to give additional info in case I'll have this crash again.

(0004317) KroArtem (updater) 2014-01-12 18:21	Reproduced it with latest trunk. It crashed when I killed the latest enemy creature with spell. (still don't know _what_ spell was cast).

(0004318) KroArtem (updater) 2014-01-12 20:29	Ok, it was "Lightning bolt" but I'm pretty sure it doesn't depend on used spell.

(0008351) Povelitel (updater) 2022-09-16 20:15	Lightning bolt works correctly. Reproducibility failed
