I've had to stop playing several missions when doors will not open because the lock never gets picked on doors - matter of fact haven't finished a mission. The green light shows around lock pick, the door handle moves up and down, that's it. I've checked the light around lock pick and it stays green [red for wrong pick]. Rarely a door will unlock but even when it does it takes a long time. I've waited so long on some i put a weight on the mouse because wrist was getting sore.
