That's kind of a critical bug, I made it to the point where I had to wait for my AI friends (Abnur, Varen, etc.) to do their thing, but they never showed up. So I went back to see if they were stuck, but nope they were gone. I went back to the port and re-entered the instance, but the npcs never showed up even if the objective was to talk to one of them.
It's a huge let down to say the least, I had fixed up my armor too and we all know how pricy that is.
Is there a way to fix that...at least until the devs patch it?
