Weapon Swap Bug

[fiftyfour5454]

If I press F to switch to my secondary while holding down left click with a variety of automatic rifles, I end up firing an invisible secondary while the real one is still attached to my hip.  It is impossible to reload in this state.  Works with all secondaries I tried, and with the rifles listed: Boltor prime, braton prime, dera, dera vandal, gorgon, karak, karak wraith, stradavar, stradavar prime, supra, telos boltor, tetra, and tiberon prime.  Again, holding down left click and pressing F at the same time with one of these rifles equipped causes this.  Switching to melee or primary and back gets you out of this state.

Thank You
