This has apparently been an ongoing issue for over 5 years now.
There are a multitude of forum posts regarding this issue, all without a solution.
Turul is stuck on Asura in ground mode but he will not aggro, has no name, and is not targetable. Without intervention, he will stay that way in perpetuity...while this may not be recent content, the inability to interact with an NM that I need is annoying at the very least.
