I just started my second playthrough of the original Mass Effect on PC, and every time I fire a sniper rifle it overheats. This happens regardless of which sniper rifle I have equipped (one is listed at 1.2 shots before overheat, the other 1.3. I'm not very far in yet).
Perhaps I'm simply misremembering, but I believe in my previous playthrough I could fire, wait for heat to dissipate, then fire again without overheating. Now it just overheats after every shot.
Is this a bug? Is there some debuff on me that's causing this? Or something else?
