Amdapor Keep bug

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.

Edited to add info and change title.

For some reason, AK allows the leader to replenish the party when people leave at the very end; this is probably unintentional, and I don't know if other dungeons do it. Also, quests and such register completion when the exit is used, hence your quest completion, but tomestones are awarded when the boss dies, hence not getting any reward.
