I don’t know what happened, but when I resumed by game today I can’t change my weapons. I’m stuck on the pistol (not the worst weapon to be stuck on). Even if I load earlier points I still can’t switch weapons. The weapon chooser moves and selects different weapons, but a pistol is still all that remains in my hands.
Did you have fast weapon switch enabled? Because without it you need to additionally Left Click to choose a weapon.
I hadn’t specifically set that, but I will take a look at that setting. Thank you!
