I completed all steps through Welcome to the Resistance for this achievement during BfA but never did the final step Operation: Mechagon - The Mechoriginator. I am now at level 70 in Dargonflight and trying to return to Mechagon Island to solo the dungeon, but there is no flight path available from Boralus. What am I missing?
The flight path is a per-toon unlock, did you do it on the toon that is trying to travel there?
you have to do the chain quest first. then it gets unlocked.
or wait till you cap out they give the portal for you instantly. no need to buy it.
