I was playing Sec. Founders Tower, as a Heavy Medic w/ a gotlung
then all of a sudden whenever i fired my gotlung the ammo would be : 199 198 197 198 199 198 197 198 (repeat)
it would hit the enemy, but it wouldn't do any damage
it fixed itself, but just wondering, WTF??!!

At least it's not a A.I. getting ten head shots on you with it from halfway across Sec Tower.

Ah, I remember this happening pre-patch. I've had it happen to me before (from both perspectives).

From being shot at, I just stared at him for a second, then shot him, quietly lulzing to myself.

From shooting, I was shooting at an oblivious player for several seconds wondering why I'm not doing any damage. When he finally gets the brains to look at the radar (or the obviously loud noise coming from behind him), he turns around and shoots me. Only happened once, though.
