I was using the broader AC Wikia, and all THOSE links there may not be up to date like the landblock page you specifically had been working on. (again, I was working dungeon -> landblock, and trying NOT to just to use the dungeon viewer). On one screen I had the PhatAC spreadsheet data file open to their list of data tabs (not as complete as yours), as well as the Wikia of Blackmire, and was not seeing those dungeons. Trying to teleport in PhatAC wasn't working, cause, well, I was sleep deprived
Long story short, I think my info is more helpful for the PhatAC file, not so much for your intentions. Some dungeons looks like one off's or special one-time event areas, so they will be tough to pinpoint.
