It's plenty bugged for me. Getting him past the second waypoint is a crap shoot in and of itself with him standing in place in combat mode indefinitely even after a fight has passed or him disappearing after you "lose sight" of him. But, even if you can get past that, he still never fully enters the last room for me; he stops either on the bridge or just past it prior to the entryway. Also, despite the previous suggestions, ANY TIME you log out/in or exit/enter the lower caves portion of the Crystal Caves, it resets the quest to the 1st part of needing to escort the guy to the camp area by the boars.
I guess after six months of this being an issue me and the select few others are simply unlucky and must wait longer. Here's to hoping it'll be fixed before year two.
