What is the deal with Highpass

[provocating]

An update on this...

The one place I did not zone a player via quest, and just used normal zone lines it happened again today. I will replace those with quest npc's too. But this was in the log. I wanted to just give some more information on it, in case someone else runs into this.

[provocating]

Now this is me zoning. The player in question was a guide, I know for a fact he uses Underfoot like I do. So it was bypassing the zone line and trying to send him to the old Highpass, although he has Underfoot and no Highpass exist.

[07-14-2015 :: 18:55:17] Zoning 'Provocating' to: highpasshold (407) - (0) x=-318.170013, y=-108.790001, z=-21.420000

I had him repeat the same action later and it did not duplicate itself. This has been a highly random occurrence. I will have a player spend hours around Highpasshold and not have an issue, then later they get in a zoning loop.
