Also wouldn't WoW return an error if it was looking for the texture in the wrong place? For example "no such texture exists" yada yada.
That was the idea in messing up the path .. there doesnt come any error. So in my opinion, the addon isnt trying to call the texture properly.
And now we come to the great question:
It does it, when i am dead ... but not with a "normal" waypoint e.g. in Shattrath. What is the difference in the code ?
