My husband (The Great Gingino) who plays on Surge informed me that a player used a minicopter explosion/fire to break into a part of his base that was still wooden/twig. Though it IS PvP, he should have been protected by the 48 hour window and has been active every day. We tested his theory and found it to be correct. (Edit: I did not see until after the fact the Witch Doctor also reported the exploit, my apologies!)
