Hi, today I changed my Ground 'Switch Weapons' key bind to Mouse 4.
Now whenever I press this mouse button my weapon switches, but in the display it disappears from my characters hands. It does however still function and you can see disruptor blasts firing from me to the enemy target.
If I use the GUI to switch the weapons you can see the gun in your hands just fine.
A weird one but totally repeatable.
I'm using an Nvidia 8800 GTS if it helps... Driver version 195.62
