Hole in the ground in Valtara mountains

Bug Name:

Hole in the ground in Valtara mountains​

Bug Description:

I was trying to kill bears for Bartali adventure log and I found place above the Calpheon shrine which allows you to walk into texture and see the structure of the Shrine, this isnt really problem, problem was that it happened one time before, almost on the same location, but I was trying to run fast to Karanda but I fell through the ground and ended up under the map dead.​

How to reproduce/proof:

there are few screenshots I made when it happened, https://imgur.com/a/P9nCDMz​

 

Its possible fix only after implemented geo engine.
