I didnt ignore contact, I simply refused it. They just wanted to get off the planet, and you cant "magic" a ship off a planet. When you surround a already alarmed force they become distrustful and very careful, I wouldnt try to make contact with a group who has guns leveled at me, I have no idea whether or not you have orders to fire when I make contact or not. As for warning shots, they dont care or know what they are, those forces were there to save the crew and salvage sensitive material from the crashed vessel, Septonian protocol. Like what happens when you back an animal into a corner, same thing happened here. Crashed landed on a foreign land and immediately surrounded, they felt like they would be killed. Yea, its fine to apply, the more the merrier :)
