This happened twice in a row(just maybe half an hour ago), I was the host doing missions on Saturn Proxima - Nodo Gap. When I mount the turret, my character just froze and /unstuck won't work, press exit to opening the menu(and melee combo and other stuffs) won't work, basically hard locking the game.
PS. Seriously, we need a suicide command to escape this kind of situations, we've been suggesting it for years now. Please, please, please, just please add a suicide command.
