I have almost 100% the game and the only thing left is one place in the hedge, which is the hedge ascent but I can't get the game to register the location. I have tried looking at it from different angles and locations still nothing...

 

Sometimes it helps to come to the right point and stand still for 5-10 seconds. The only problem is to find this point.

J ai le même problème avec le mix.r du haut jardin impossible de le découvrir j ai essayé tout les angles possibles et rien ce passe

I’m having the same issue with this location it’s the only thing i need to 100% if you happen to find a way to unlock it please let me know.

Perso j ai fait un rapport de bug et obsidian m'a répondu avec un questionnaire et un partage de sauvegarde pour voir se qui bug, je vous dirais le suivi. Je vais informer dans ma réponse que je suis pas le seul. 

Je suis dans le même scénario.

C'est le dernier point qu'il me manque.

 

I am in the same scenario.

It is the last landmark that I have to discover.

Thanks, and sorry again for the frustration that this issue has caused you all!

I am just responding to find out if there was a patch or a new method. I'm on the final quest and I just have to unlock the hedge ascent and it isn't unlocking for me.

it’s been 10 months and you’ve still not patched this hedge ascent is still undiscoverable i’ve tried every angle every position and i cannot discover hedge ascent i’ve give you a copy of my world in order to fix it that was 10 months ago

I have the same issue, tried every position pausing for for 10 seconds each, no result, the Hedge Ascent is the very last place I need to complete the quest.
I think I remember the game showing that I discovered the Hedge Ascent early in game but now its missingi

Platform Windows: 11
Game version 1.3.5.4372 (though Steam)
Multiplayers (All PC on steam) but I am currently trying to finish the game alone.
Difficulty level: Mild

With the latest patch (1.4.2), the Edge Ascent icon shows under "Hedge"  sites & wonders but the quest to discover all sites and wonders still complains there is one missing. Do the math, it comes to 108!
Platform: PC
Multiplayer

I also have the exact same issue, in the data I have all 108 but the quest is at 107/108 and the map is missing the icon for the hedge ascent.
