i was playing an online match against 3 adaptive ai and i was letting people observe. i think there was only one observer though. so im about 28 minutes into the game and i hear an explosion as im trying to upgrade a mass extractor and "commander under attack". literally my entire base blew up except the walls i built. some of my stuff wasnt even in range of the explosion radius of my commander and it still blew up. are observers able to interfere with a game? what on earth would cause this?
