If you have questions whether a dungeon is supported, if it plans to be supported or if the dungeon isn't working, the Dungeonbuddy support thread would be the appropriate place to ask these types of questions.
It's not a fail, its called TEST RELEASE.
Before WoD is released and got 2-3 updates I am pretty sure there is a lot of work on the HB side and also for the 3rd Party Developers writing CRs and Plugins.
Until old profiles are fixed or new Dungeons are added it will take a couple of weeks I guess. Atm. a stable release of HB has priority.
The developers work night and day atm. but WoD is a big addon adding a hell of a lot of new functions and features.
Before everything is like before and every new stuff until level 100 is added it will take a while.
You can help buy reporting HB bugs in the Test Release thread or Singular thread. For the rest you have to show patience. Sorry.
