I’ve just started with this game. Enjoying it very much. Anyway, I was out bear hunting. As it got close, I wielded my FN FAL which has a suppressor, an adjustable stock, a rifle scope and a masterkey shotgun attached. As the Bear closed, I switched to the masterkey using the alternate fire button. Then I fired it and the game closed. Thankfully, I’d saved fairly recently. I’ve tried it three more times and it closes each time. I’m using version 0.8. Cheers dev folk.
Bug has been around a while. Affects the M203 (underbarrel grenade launcher) and the regular underbarrel shotgun.
This has been fixed in the experimental.
