We played this (extremely interesting) 3v3 with the NW clan. In the late game they had queued up some catalysts and we had some halleys queued up. We finished the halleys first, and threw it at one of their catalyst-spots. The result was a huge crater. Then they just proceeded to build a catalyst mid-air in this crater, which... I think is a bug I know people have discovered it before, but I think it's worth some attention. It's kinda... bad that you cannot counter the catalysts at all, not even by throwing a planet at them this is the game: http://www.pastats.com/chart?gameId=277255 game id: 10647933482866145843
Yeah I think @jables mentioned there was a fix due for this (although it might take a while- not an easy one apparently)... Edit: Also so despite them getting the metal planet you managed to win anyway? Nice
