Not everyone is on the alliance's official forum, so this is basically what happened.
This is from Cnidarian, a General from Aphelion:
"As most of you are aware, the solar rail initial launching failed.
Let me start by explaining that Aphelion had our rail finished and immediately tried to deploy it at Akkad, Eris. Despite this, our rail never appeared in the selection menu and we were unable to use it anywhere. Keepers of Kerberos experienced the same thing.
Aside from that, a wall of red text appeared right before everything happened and several suspicious clans/alliances were able to claim most of the system before we finished ours, even though we rushed the lab using platinum and saved time wherever and however we could.
We have submitted a ticket to DE asking for an explanation.
Regardless of what has happened we will proceed as planned and attack Akkad, Eris unless we vote on a new area to conquer. We can contest areas in 24 hours after the cooldown is over for their rails.
There will be a discussion about this among representatives, and I expect them. "
