I've seen Flight Path tutorial here (Flightpath Tutorial by rup33rt) And I decided to make it.
My first attempt was on map 1, more exactly in Mulgore and all worked and works. :D
But I wanted to add a second Flight Path in an another map : 606 (QA_DVD map).
I did well everything and know that there is no errors in my DBC edited files. I've updated SERVER & Client, but it still don't work.. When I Click on NPC, it doesn't show the flightpath interface, it does nothing.. I don't know where is the problem, can anyone help me please?
