Hi all,

As mentioned in the following thread: Darth Malgus - Belsavis World Boss not respawning, our team is currently investigating this bug.

This issue seems to occur (at least in one case) when players kite the Primeval Destroyer's adds away from the boss area after the boss has been killed. Until we can fix the underlying issue, you should try to kill the adds even if they're still alive after the boss has been defeated.
