Hi,
So I have a NavMeshBounds volume on a small ship in a world partition map, the ship doesnt move but it is set to dynamic (with modifiers) as I allow players to place new actors. It is the only nav mesh on the entire map.
If the player gets far enough away from the ship, naturally things start unloading behind the player which is expected.
In the editor this works fine, but in production/development build I get a fatal error with the below details.

If I set the navmesh to static it works fine so clearly a dynamic only issue but I wonder if anyone can help me understand the issue or know how to fix it?
