I'm not sure if anyone else has this problem or it's just me. When I'm playing in Lockdown fighting someone, my weapons suddenly change on their own.

I swear I'm not pushing a button or scrolling on the mouse wheel to change them. It only happens when I'm fighting another player or chasing someone.
When I'm fighting with my sword it always turns into a gun. Sometimes when I'm shooting someone or just spamming my polaris it suddenly changes to a sword.

This problem really ticks me off because I get killed from this every once in a while.
