I have gone through this dungeon twice now. I get to the final battle, and all NPCs have green names, and will not engage for the final battle. I have reset the dungeon twice, and still cannot complete it, as the NPCs refuse to engage in the final battle.
I tried submitting a support ticket, but the site says I have to email help@kingsisle.com instead of offering me the usual ticketing system I am familiar with (was it removed?)
I don't have access to my email right now as I am traveling for Thanksgiving.
I was with Zeppers. Captain Winters would not appear for the final battle, so we reset the dungeon and changed realms (just to make sure it reset). Tried it again, and alas, still didn't work.
