Not sure which developer was responsible for those 4 NPC's handing out those quests but bravo. I currently have 5562 of the Anchorage Chit currency items, I found it very enjoyable and relaxing to just rinse and repeat these quests. Sad to see them coming to an end. Thank you, I hope to see more of this in the future.
According to the write-up by Denmother, when all 4 are done, Whilhelm will offer a single quest to allow people to continue to earn coins if they desire.
But I still haven't been able to do the entrance quest on my Adv level 12 because they made the final quest item lev 20 req. They let you pick the quest up, hack all the way to beastie but then you discover you're at a dead end And I ain't gonna get chit!
