Don't believe this is a problem any longer. I'm able to clone, build with EasyBuild, and get the binaries and conf files without issue.

At this time, Rel 21 is the supported version. Rel22 is still in development.

Confirmed. Still an issue as of 2022-02-18.

Blinking in Kalimdor takes you to:

Blinking in Outlands takes you to:

Common theme is that the blink spell teleports you to 0,0,0 on the continent.

Confirmed - still not working.

Notes
Creatures/triggers are already spawned. Tested killing one with .die, does provide quest credit. Using the  provided item at the creature/trigger does not provide quest credit.

On MangosZero, tooltip states: "You carry the Touch of Zanzil. The poison courses through your veins. Seek aid!"

Based on WowHead comments, it is supposed to do the following: It reduces your Agility by 15 and enemies can see you through stealth as if you were not even stealthed. 

However, by casting "Stealth" it removed the poison permanently.
