Carbonite II and old world instances
 

The instance maps for a couple of old world dungeons still aren't working with Carbonite II (I'm using the 5.4 alpha currently on Curse). Wailing Caverns and at least one other that is escaping me at the moment (unfortunately I leveled past a couple of the trouble dungeons before thinking to report the issue).

Is this a known issue, or do you have to tweak something to make them work?

Thanks!
