"Doomfire: Ro's Sweatshop" not at the Moors of Ykesha Location

I just confirmed that the portal is there, on the Isle of Refuge server.

Keep in mind that just having the quest "Combusting at the Seams" is not enough to see the portal. The portal's presence requires a bit of advancement in the quest.

What does your quest journal say to do?
