Falling through top layer of map mesh around set city

Game mode: [Online Private Server]
Problem: [Bug]
Region: [Here]


Have a problem where I can only stand on the 2nd layer of rocks on the mesh and if I go on any unsupported areas I fall until being spawned into desert spawn.

I tried running back from desert to see if it was tied to bed spawning and I still fell through when I neared the city
