Fix the quest dudesss. WTF even after the dwarf's attack all three kegs have some amount of HP and yet " Down With The Dark Iron" quest doesn't show up. just simply make the quest available for everyone so that they can just complete it.. Don't want to report in bug tracker.. why... because people need to vote, then it gets prioritized , then waits in line to get fixed.. by that time it will be next year.
Restart the server maybe so that quest becomes available.
