If you sprint, climb, go prone or get up from prone, or vault, etc it cancels a reload. Always check the mag indicators in the bottom right to see if you have a mag in. (not saying it's not a bug, just putting it out there)
I mean. This "more players less fps" issue exists in almost every game ever, so are we really surprised?
I get the feeling this only happens to new players who tap "sprint" when their reload is almost done (which cancels the reload)
Do you have an extra-wide screen? I find it kinda sad they didn't fully model the guns. Having what they expect to be just offscreen not modelled at all will of course lead to issues like this when leaning with gun obstructed.
Can't wait until they fix this. This is probably the most noticeable bug in the game.
