So the first time i was attempting to get the achievement, everyone i was playing with had not done any side to the easter egg. So we decided to do richtofen being as we found it easier and got the achievement.

So here is the problem... I tried to help someone else complete the richtofen side of the easter egg and we got to the point where you have to use the siliquifier on the orbs and after two whole clips of the gun on ONE orb it would still not spin. So i figured since i had already completed richtofen's side that i could not again and would have to do maxxis. Which when we tried maxxis everything was working and advancing with the steps but we did end up dying trying maxxis's side.

So the question is... Can you not help someone else complete the easter egg of the side you have already done?

I do know i was host though and am not sure if that had anything to do with it, but by the time we tried again with a new host we could not find a decent fourth to help so never got that far to see if it was a host problem?
