My character was recently faction-swapped. I believe somehow this affected phasing for the early 11.1 campaign quest Pamsy’s Prized Pump.
The NPC (Pamsy) does not acknowledge that my character has a quest to hand in, instead presents her normal dialogue options. Also she appears to be in a different spot from where the quest marker indicates on the map.
Relogging, leaving the area, or abandoning the quest has done nothing to solve the issue.
I tried doing the quest on an alt and I was able to proceed without issue. The problem only affects this character that had a faction-swap during the Siren Isles patch.
