So went ahead and have had Supply Line Mastery unlocked now for a few hours as I tour the various Central Tyria zones working on Pact Mastery and collecting Skill Points on my Revenant.
Rewatching the reveal, I noticed they said these vendors would travel (for safety) but appear on the map.
With 5 zones left to go (eastern edge) I have yet to see a single vendor yet. I also checked with my character with 100% map completion to see if they show on the global map and they do not (that I could see).
Has anyone had success finding any yet or is it bugged and not showing up?
