I got interrupted by RL while accepting the merchant job quest. I already had written down the destination (Byalan Island), but I never got the serial (tbh, I have no idea if I spaced out and didn't see it or if the game didn't give me one). I wasn't too concerned, as there are only 2 serials for Byalan Island (3318702 and 3543625)...but neither works. And there doesn't seem to be a way to simply reset the whole quest.
Any ideas what to do now?
