Auric Basin invisible wall

[Noa.7490]

North-East of the map, north of the Razorwing Hero Point challenge, there's a climbable tree which allows us to reach Burnisher Quarry (where there's a vista, a PoI and an easy Hero Point). Unfortunately, on top of the tree is an invisible wall that keeps us from reaching the area, we have to go around instead. That invisible wall didn't exist before and appeared suddenly months ago. I figured that somehow, someone would do something about it but as of today it's still there. If, for any reason, Anet thinks this way should be blocked then perhaps a visible obstacle would be better than an invisible wall.
