Mercenary stops shooting

Whenever I roll after finishing my ammo, it takes so much time to reload and even it gets stuck at a point that I cannot shoot. I don't know how many times I died because of this bug. It is very frustrating, especially considering we dodge because we are in a circumstances that we cannot survive most of the time, and not being able to shoot doesn't really help during those critical moments.

It's been nearly a year since it is first mentioned on the forum. It is very disappointing that it's not fixed yet...
