@fubaWoW Was this before or during The War Within pre-patch event? And do you remember what world quest it was, or was it just any that gave the error?

phu... hard to say right now
it was random that i ran into a worldquest from legion and the error popped, so i reported it :D

i can test it later if i do not forget ^^

There is a chance it was caused due to issues with the War Within prepatch event not registering correctly that the API was changed already so certain functions were no longer available, and this should be fixed in the 1.2.2-release on curse.

I tested quickly with a random quest I saw on the map in the area:

But if you remember what quest it was or encounter it again please let me know and I will see if I can fix the issue!

I am going to assume it's fixed since the 1.2.2 update. If people still encounter this, please make a new issue and let me know which quest you got it on, so I can test it as well.
