Me and my two other friends are having some trouble with the Zombies in spaceland step. It's three of us and from some reason we cannot get the seti com step where you place down the things at the spots around pap and start the boss fight. We place them down quickly under 5 secs and the boss fight doesn't start. It's me who starts at pap, my friend hits space and polar, then I hit keplar. We've done it a few times and the boss fight doesn't start.

Any help?
