I had the same problem, and I have a bad feeling that it's some sort of "speed trap" like the cops use on the highway. Thank the gods that MQ2 blocks the crash report that is normally sent back to SOE.
They also placed named werewolves up in some trees Kithicor at hieghts no one could get to, with or without lev... I just can't help but wonder how many poor saps have warped to them and killed them.
SoE has also been putting items under the world and leaving the graffic for them above the ground.
It would be a simple matter of checking the spawn points and logs of the ground spawns under the world or the werewolves that no one can get to....
these are just a couple things I have noticed since the patch for the halloween event...They are only my opinions, my quazi educated guess based on some very strange acts on SOE's part.
I honestly hope that I am wrong in my guessing.
