A player reported having a problem with Xander not acknowledging him on returning for payment ("your name" is taking the quest) - odd, but go figure.

As a potential work-around to this , I suggest the following: 1. Find someone who can take the quest 2. All members of the original party log out 3. Have the person from 1 above take the quest (script checks for players online, and if they aren't, the quest is cleared and player requesting it can take it) 4. Re-log in with original party 4a. DO NOT talk to Xander at this point 5. do the quest, kill the boss 6. Return for payment, the recruited individual talking to Xander

That has worked when it happened to me. While I have no idea what exactly is going on that Xander forgets the original player(s?), it's a work-around to try.

May be an issue with player logging out/crashing when completing the quest but before reporting to Xander.
