I don't know if anyone else has encountered this problem, been happening to me for a few weeks now.

I use my last weapon used key alot, like to blink and swipe, or switch from lmg to pistol, not a big fan of the normal weapons keys.

What happens is it just stops working, i switch from lmg to pistol, then hit it and nothing happens. Sometimes it only partially does this, like it won't switch from lmg to pistol, but it will switch from lmg to welder and back. Also sometimes if i drop all my equipment, pick it back up it fixes the problem, but most of the time it doesn't. I have also noticed it almost never happens in combat, mostly happens in classic.

I have completely uninstalled and reinstalled, and it still happens. It's making me crazy, any feedback would be much appreciated.
