Nostalrius Begins - Quality wow vanilla realm (1.12)

I get this error from time to time. Anyone know why / a fix for it? Im not sure what it is calling for or why?

are you using Questie?

edit: just looked it up, you are using Questie and Questie is causing this bug.
I've had reported this to the Questie devs few months ago, but I've never tested their resolution and replaced TipBuddy with my own code. Guess their resolution does not work.
