Since the last update I’m experiencing a problem with my fire button. YES, my fire button, our most important tool in this game 
Sometimes, e.g. after I throw a sticky bomb or deploy my health station, my fire button stops working. I simply cannot fire my weapons anymore. After pressing my buttons in an uncontrolled way, I sometimes get one shot of my primary (shotgun) or my secondary (MP) goes into autofire mode - it just keeps firing without me doing anything.
This seems to happen at random times during a match.
If I die, everything is back to normal, until it happens again.
Reclaiming one of my stickies also seems to fix the problem for a short amount of time.
So far I have checked my local files through Steam and tried reverting my settings back to default, but so far no luck.
Edit: Propably should have posted in the bug section, sorry.
