Logged in on a regular Experimantal Server after the Navemash implementation I was equipping my Sks, run a few meters, hold right mouse button - character was throwing weapon. Searched and found it again. Left server immediately, tryed next one. Join another server equip Sks, run a few meters, hold right mouse button - char was throwing again - weapon disappeared.
Later with pistol equiped run arround and hold secound mouse button, char was throwing pistol. This time pistol was hovering in mid air at the point of throwing. Had this with a Shootgun and a Pipsi, too. But stuck in throwing animation with these.
So its was big issue for me. Made DayZ unplayble, game breaking. But I figured a workarround out. Had to rebind "Hold breath".
