Does not always happen at this quest giver.

Seems a little strange to me that the error occures in function GeneratePlayerLines() because it's a NPC. I walked to the quest giver and got no error if hovering over this unit.

But in the case UnitRace() doesn't return a valid race, the error you mentioned occures. So I added a check for this case. This will be included in the next release. 👍

It is random and maybe a player walked under my cursor. It happened later just walking around Dalaran, I didn't notice who my mouse was on.
