When I go to dig a trench with ACE, and it gives me the instructions (left click to dig, scroll wheel to turn, and right to cancel) I cannot left click, or else it shoots my gun (or does nothing at all). The same goes for any other activity involving the similar instructions, I can't fuel things, can't place down items (like portable lights), or anything. I have tried to put all my guns away, still doesn't work, just click and boom nothing happens. Anyone know how to fix this?
