A rookie goof up. I’m sure you might be able to correct this mesh flaw.
You could include a screenshot of the map position and send that here: Contact Us — Conan Exiles Help Center
Might increase the chances for a fix.
I wouldn’t exactly call it a “bug”.
It’s a technical goof how the landscape was laid out with the upgrade.
I don’t think there is going to be any easy way to fix that.
Right in front of the King’s Niche is the location. Can’t miss it and I don’t know how anybody could have overlooked that one.
It could be troublesome if somebody finds out how to use it to get under the map. Not a bug per se, more of an oversight. As for the fix, quick and easy, place a small rock there. Still valid to be reported, as Inflexion is probably happy to fix these things 
Over the years there’s been plenty of these that get fixed. Submitting a report lets them know so they can add it onto the docket and eventually fix it.
Okay.
Have it your way.
Go take a look for yourself and report it.
I’m going to be blunt about this.
I am not going to fill out that form.
Iv been seeing these all over the place too many to count so I just look the other way. If it’s not textures not lining up or weird triangle points in the desert then it the spot in the noob river in the water where I just drop down to the river floor when swimming they lets me just stand underwater catching my breath.
Since I have mods installed I don’t report nothing anymore only cause I don’t wanna spread false info to the devs.
