I think maybe I found another bug? I joined the canned catfood coop server briefly to play some khami std, got in the A-10, bombed some poor unsuspecting player on the enemy team. When I switched to the rocket pods, and fired at a rather large group of inf inside chemical facility, the sound was as if I was firing rockets at 1500RPM.
Maybe this was a one time event? I don't know, I CTD'd whilst landing and gave up for tonight lol.
EDIT: If only the rocket pods had more ammo, and actually fired that fast.
