Hi, only just started playing this game, on a level where you pick up the stealth scarab at the top of some stairs, there seems to be a bug where sometimes it won't let me switch to semi automatic, if I die then pick up the scarab it let's me do it, if I quit and start again and pick it up that sometimes sorts it out too, anyone else had this?

i have had it a couple of times that when i switch to the shotgun underbarrel i cant switch back...even after running out of ammo.
