I'm testing this by using questG04Nemesis but it didn't behave the same on the two accounts I tried.
I think the difference was that one account I picked up the quest by hand and showed "started" and on the account that the script unlocked the guild and picked up the quest, it didn't change and stated "unstarted".
I will need to check this again but it will need to wait until I ascend again.
It isn't a major bug, I simply put all the Epic weapon in my closet before starting the script and it seems to work.
