I hate to start another topic on the AC130 gunship but I figured since I got the one specific bug narrowed down it might help the debugging.
What happened: I was testing out the maps with some bots. I had the C130 set for 2 kills so I can test out if the airship works on each map. Anytime I was playing S&D and earned the C130 in one round and then tried to use it in the next round, I would be walking around shooting with the C130 weapons (pretty cool).
I couldn't tell if I was invisible with the weapons, well because the bots don't have voice chat.
