Your instance is full.
We had joined the right way, with our warband leader joining the queue first. Straight away it pops up saying our instance is full. Not one single person from our warband is in Altdorf. We've been waiting ages now.
So despite having got to Altdorf, we can't actually go there. After 1.2.1 getting to IC or Altdorf on Karak Norn is hard work, we've got a very competitive server these days. Yet all that time and effort for nothing. And I've just heard that Order players are complaining of the same thing, so they can't get in either. WTF? Both sides have warbands of players that want to fight in the city siege, but the game won't let us.
To quote an alliance member:
A "your instance is full" pop up message is not a valid end game
Mythic this is not good enough. I have had to post too many negative things lately, I don't like it. Sort it out.
Update! We got in by having everyone leave the warband, queue solo and then reform it inside. Ok its cool we got in, but that's just bloody stupid. Our instance was full, yet it let us in solo with EXACTLY the same number of players to EXACTLY the same instance. LOL :P
Can't get back in, no matter what I try :(
Finally got back in. Wish I hadn't tbh. We got Lord on last stage of the PQ to 11% and the zone just crashed...
Forgot to mention the CTDs earlier. Sigh... What a waste of my time this was.
