I do have ELVUi installed as well.

Exact same problem. It happens on any map where there should be drawn lines for a rare's route. Only happens if I load up when already on this map. Works fine if I enter the map after flying in from somewhere else. 100% Repo Rate: camping Time Lost Proto Drake. Route lines draw correctly if you load into Dalaran and then fly to the mountains. Route lines fail and error thrown if you log out then back in again and then open the map. Every time you open the map.
