Amdapor Keep bug

[Saibogujimon]

After an unsuccessful attempt at the Demon Wall in Amdapor Keep, I left and decided to try and join a Party in Progress in hopes that I could join a group that was past said wall of demon-ess. Well, to my surprise, I joined into a group(as did one other person) and the dungeon was completed. The victory music was playing and all I had to do was run to the end of the dungeon and leave via the "teleporter". I received full credit for the dungeon(I required it for both A Relic Reborn and my Grand Company). I received no loot or tomes of any kind. The hoplite ring I currently have was from the previous AK failed attempt. I'm not sure what caused this bug and I did not try to repeat it. It has been bothering me since it happened. I hope someone looks into this. Thanks.
