Encountered a glitch today - at the end of this mission (forgot the name of it but it's the one where you drive the moonbeam van around and cap ballas and vagos I believe, ending with 3 helicopters in the sky) you are supposed to destroy the moonbeam with the gas out of a jerry can. Well the first time I tried to complete it everyone just used a rocket launcher on it. It destroyed just fine but the mission acted like it wasn't. The second time I warned people to ONLY USE THE JERRY CAN, no one listened and proceeded to toss sticky bombs and grenades. This time it completed EVEN THOUGH we did not use the jerry can, so this mission seems inconsistent with the completion requirements.
