Obvisouly for me, the new change concerning the pre-registration is not working well.
As Sacroima said, the first morning after the start of the server, I made some observations : 2 large corps in one city and two other in other 2 towns of the same region. By large corps I count only the players who had actually start the server on the morning.
If they could start on the same city or region, they were pre-registered, no ? So the system allowed 2 pre-registrations in the same town (meaning 40 players) and 2 more corps in the region meaning a total of 74 players.
Meanwhile, one other corp was forbidden to put a foot un a region with 2 large corp and a smaller (meaning 50 players at all).
My purpose saying that is : the new system is clearly bugged. Where ? that's to the developpers to say.
