3rd quest bug!

hi today i did marlon quest for elfs: ring of honor...and skiped the next one that marlon gives because i'm not a BK.

after finalizing it i went arena to lvl up till lvl 380 to next the next part.

i typed: /move barracks and talked to the priest and accepted his quest. my quest log was actualized with the new quest...


after that i went icarus and started killing fenix... change server some times and after killing almost 100... i thought it was acward the time the item was taking to drop... so i opened my quest log and realised that the quest was changed to the ONLY BK marlon quest

i bought the stone just to be sure but as i thought i wasn't able to deliver it.

Finally i returned to the barracks to be sure i had accepted the quest and this happened...when i accept the quest it's updated:
...
but everytime i go icarus,aida or tarkan the quest is changed:



is that the cause of the drop delay or is it normal and i should ignore it:
