Correct me if I'm wrong but usually, the daily Regular Customers quest is activated upon completing the "level 2 rune making quest" by reaching level 18. This was still the case about 1 or 2 weeks ago when I leveled other alts. But yesterday, when I reached that point, I never received the latter quest consequently preventing me from doing the former quest too.
What is going on? Is there a quest that triggers it? Is this an anomaly? Did the devs remove/redesigned it in a recent patch?
