Can't pick up grenades, molotovs?

[Helmet Hair]

Been doing a couple of missions now, but can't use or pick up molotovs for some reason? Do they get unlocked later or have I missed something?

same problem. Think its a bug, as the grenades cant be picked both by circle weapon menu (locked) and z button even if rebound it.

I cant pick up dead bodies, someone else could not shoot, another one not sneak ... seems that by random a few buttons stop working 0o

some buttons are only working when you press the Tastatur-Key and the controller key at the same time.... im searching for this about half an hour now.. but no thread found atm... that suxx and makes the game unplayable because I cant switch weapons or open the menu...

Same problem, can't use any throwable...

i had this for awhile. dident even seem to be able to buy any.
then i realised i wasnt pressing the cycle explosives key "Z" by defualt which switches between explosives.
by default youre not using explosives so unless you switch it always appears in red and like you can pick any up or throw any.

press Z to swap between them.
