I was messing around under 'controls' in settings, then suddenly mouse2 did not work anymore. I have no configuration showing for left hand. I can't use mouse2 to block anymore either. Anyone know how to fix this?
You either accidental assigned the "mouse 2" to another key or you asigned something else to mouse 2 and thus, the original "mouse 2" command has no key. If you go back into the controls there should be a reset controls button or something that changes the controls back to the way they were. If not, you will simply have to re-assigning the "mouse 2" control yourself.
