HP+Vista in Burnisher Quarry, Auric Basin blocked?

Hello yesterday i was helping a guildie with HPs from Auric Basin and we encoutered an invisible wall above Vinetooth den POI (east). At first i thought it was made with purpose but after thinking about it... We needed make our new way here which would be impossible without raptor's long jump 'cause he is fresh new player and doesn't have ley line gliding. I draw how normaly we would proceed.https://imgur.com/DWBXVKchttps://imgur.com/b5Rhqzc

https://wiki.guildwars2.com/wiki/Burnisher_Quarry_(hero_challenge)There are three ways to get to the HP, if there's an invisible wall in Verdant Brink it's likely for a reason since those maps weren't made with mounts in mind. You will be able to get to everything in Heart of Thorns maps without using the mounts at all. In this case, if he doesn't have Ley Line gliding or Nuhoch Wallows masteries, he'll have to take the third path.

The third is to start from Eastwatch, ascend up the mushroom steps to the Notice to Trespassers hero challenge, climb further up into the nearby trees by the chest, glide over to another root, and then perform a short jump over on to the roof of the cave visited during Prized Possessions, from which point you can glide down into the passageway leading north

Found a video of someone getting there too:

That's the problem at 2:01 you can see he can go past but we couldn't we were held by some wall, we couldn't go further.

Oh, thanks for explaining didn't know. ^^"
