There are two current issues:

First is the Groza, if you drain a mag completely empty a bug occurs where the animation of reloading does not show and even if you put a mag in it will not cycle. You have to single chamber a round and then you can put a new mag in and the gun will work. A big shout out to H4nzO for finding this.

Second there is a extra animation (burst fire) for the M1A1 Thompson that was not intended to be there. The extra animation has no sound really and shoots single fire, full-auto and single fire works fine just cycle past it.

Both of these issues will get fixed in the future so please hang in there with me :)
