The path to the vista is being blocked by an "invisible wall", so it can't be reached. This issue makes it impossible to complete The Bloodtide Coast Map...
I am having the same issue, i logged it with support on Tuesday this week and have had no response at all, do these even get looked into?
Nice to see a speedy response to this from the admins!
Still blocked by "wall".
There's a few threads about this vista being blocked in this one - https://en-forum.guildwars2.com/discussion/5818/compilation-of-locations-blocked-by-in-visible-walls-map-completion-jump-puzzles-achievements-etc
