Only posting this because it happened twice in 2 days...
The quest could not be turned in after killing the matriarch. Everything went smoothly, there were no lag issues or anything odd about the events of the quest, and even the remains of the matriarch dropped and were picked up OK.
Yesterday, a DM re-spawned the matriarch so it could be completed. Today, no DM was available.
I know that if a summons or companion (etc.) deals the killing blow to the matriarch, it can't be completed properly. Don't know if that is what happened, but I'll put it out there anyway.
Additionally, if she is killed by catapult fire, the quest cannot be completed.
My char was the only one fighting the matriarch, both occassions she died by a blow from a normal sickle, though it was 2-weapon fighting (therefore, it could've been the 2nd attack in the round both times, not sure.)
Was it laggy when this happened?
It could also be put down to DM possession, although, if you say there was no DM that makes my point redundant.
Was it laggy when this happened?
No, both times there were very few people logged on, and the system was gliding along smooth as glass. Excellent performance both times, in fact... if speed could prove a factor, it would be more likely the system were going too fast. :P
My uneducated guess is that perhaps this happens if someone prior logged out without completing the quest?
One other oddity is that I re-entered the quest area after discovering I wasn't able to close it, and discovered one new set of rats (about 6 of them) that weren't there before. I killed the new batch, and tried closing the quest again -- still no luck. (When I do the quest, I always kill all of the rats before I exit -- just to be sure none are left behind and cause server lag, although I don't know if that would really happen... I kill them all just in case.)
OK, a new twist.
Today, my character used catapult ammo, and managed to take out the Rat Matriarch with one shot (incendiary).
Of course, this meant I couldn't close the quest.
However, DM Scotty respawned the matriarch for me, and I killed it with a melee weapon. Still couldn't close the quest! I ended up cancelling the quest, and Scotty manually awarded XP/gold.
This quest seems to have some odd issues.
Pup I know that if a summons or companion (etc.) deals the killing blow to the matriarch, it can't be completed properly. Don't know if that is what happened, but I'll put it out there anyway.
I've seen on 2 occasions when the NPC summoned object killed the boss and the quest ended as it should... but of course i've also seen other quests not end that was as well..
