I use LoD Feature with WowAceUpdater but, I have un little problem with Outland Instances. I'm on a French Client and Outland module doesn't appear in Bigwigs.
Observed the same on enGB client. Finally I have found that the reason was in BigWigs_Other module: it was replaced with BigWigs_Azeroth + BigWigs_Outland, but all those auto updaters don't seem to be aware of that; as a result, there was some kind of conflict (+ error that BigWigs_Other::Onyxia cannot be loaded due to missing translation). After removing that dir, everything started working fine.
