I have experienced a sound glitch with the crossbow. It was present in the 2012 mod release as well, and it’s still not fixed.
Basically the reload sounds don’t sync. with the animations. (Simple as that).
It’s a pretty minor glitch, but after you notice it, it becomes annoying. Didn’t play the game since the latest patch, so I don’t know if it’s still there, but in case it is, there ya go. Also I think the crossbow didn’t have sprinting animations (the last time it didn’t have anyway).
