So I was playing up until "refueling base" with the lithium mod, had no issues up until this one moment: There was one of those Dark Energy Doom guys I came across and I found a super weapon Dark Energy Rocket launcher not long before (forget the name but it shoots out a beam of light or fire and bullets) so I decided to use it against him. Killed him but when I went to pick up the item he dropped the game crashed and I got a fatal error. I tried multiple different things. Tried running away and quicksaving before fighting him and I got the same fatal error crash upon trying to save. Not sure if it has to do with using that dark energy super weapon or picking up that item he dropped but I can't seem to play with the mod now, at least on that save file/character without it crashing with fatal error. I'm going to try starting over with a new character but figured I'd put it out there. Also i'm using GZdoom build 4.14.1
