Hadn't seen this before, so I thought I'd mention it.
Playing Plunder, last night, with like_whoa_dude, EpicLeon and angrybumblebee1. Someone on our team, not sure who, carried a Propane Tank into the lower level of the Temple. When he ignited it, it kept blowing up, like it was making new tanks and exploding.
When it finally stopped, there were hundreds of pieces of propane tank all over the lower level. Hopefully someone from the game will post it somewhere.
