I am having some serious issues with my weapons 'malfunctioning' in multiplayer:
If I have my gun set to full auto and I hold the trigger down it may fire any number of bullets before stopping for no reason (ammo remains in the magazine). This issue has led to many, many, frustrating deaths.
The weapon may simply fail to fire entirely when it is loaded and I click the mouse.
On semi-automatic the weapon may fire 2-4 time for a single click.
These issue are definitely tied to playing over the internet because they are non-existent in local play. I will say that I have been having other issues with the network that more than likely are on my end such as lag and disconnections. It often takes 2 minutes for the server browser to become populated with servers even though I can quickly connect via matchmaking.
Is there any way to resolve any of these issues or are they at least known to be an ongoing after the most recent patch?
