The option for the quest is not always in the dialogue.
Even when it is present the quest giver will not allow to take the quest. Receiving the OOC message 'Maximum Party Size Not Respected' even when trying to take the quest as a singleton or with a small party of the appropriate levels.
I wonder if its an area issue. There are a lot of people in that area right now. Is the NPC thinking they are all trying to take the quest?
Should be fixed now....
I'm still unable to take the quest on my level 3 PC; The first time I talke to Murmick I get a dialog option "[Quest] About this house...". Clicking that option ends dialog with no message. The second time I talk to him, I get the initial "Who are you" option, but after I click that I immediately get "Maximum party size not respected" twice in the log window, despite the fact that I'm a party of one. Also, the "[Quest] About this house" option isn't available during my second conversation with him. The option shows back up during the third conversation.
As of this reset I'm able to take this quest and complete it.
