Just something i came across in one of my games using the latest 0.9 version of OpenXcom (+original Microprose disk version) that might relate to the new 'instant' grenades.
I've only had one CTD so far and i think it might be due to this setting? I was having a typical mission (lots of dead and dying troops) and as soon as i hit end turn i got a very quick message box about one of my guys either dying or going unconscious, then i heard a grenade explosion sound effect play, then got a CTD + windows error box (OpenXcom has stopped responding and closed etc).
I think what might have happened is that it was one of my guys that was already wounded (so bleeding to death) and i had given him a primed grenade but not thrown it on that turn. He went unconscious then the grenade went off during the alien turn or very close to that.
I really like the function of the instant grenades, it makes them nicely effective, but it might have an issue for the exact scenario i had?
