Added issue regarding Abdhaljs Isle-Purgonorgo.

*EDIT: Jan. 22, 2019 2:00 (PST) / 10:00 (GMT)
We have looked into this issue, but since it will take some time to address, we have taken the two NPC "Tillecoe" and "Afdeen" off the game during the Jan. 21 maintenance.
We are planning to address this in the March update. We will restore the NPCs to their proper location when the issue is addressed.
