I attacked planets 80 at 10:45ish EST today and the attacked failed during launch. Then planet 80 looked like it was under UEF attack by 4 UEF players. I didn't take any further action (I was looking for another team mate) but then the game launched... and when it did, it was me + 2 allies + UEF on a team against an aeon. One of the aeons on my team had UEF defenses on his side, at his starting position, under his control. When the UEF guy recalled, we killed the enemy aeon. This, somehow, resulted in UEf gaining control over planet 80.

Edit, apparently our aeon attack was recognized and shown on the GW map as a uef attack? we have uef ranks next to our aeon/seraphim names, and it had the blue attack indicator, not the green one.
