So i believe it may of been update .44 or something along those lines. But around this time i noticed that zooming in sometimes caused my camara to lock (in zoomed position) also (and this happens very often) when i swing my melee weapon sometimes the character just keeps swinging non stop and i have to spam left click to get it to stop.
it happened when i uploaded a version of experimental and i literally had no control of my character. its hard to describe he would run the opposite direction of the button i was pressing. I noticed some issues stuck around when i converted back to stable.
I have deleted and reinstalled the game. Ive even deleted steam. Deleted Dayz documents folder and reset controls to default. Not sure if there is some steam files that are left over even after steam has been uninstalled but im scratching my head with this one.
