NullReferenceException: Object reference not set to an instance of an object

assets/prefabs/npc/scarecrow/scarecrow.prefab failed to sample navmesh at position (-152.2, 0.4, 817.8) on area: Walkable

I have been trying to fix this for the past few days and nothing is working. 

Failed to create agent because there is no valid NavMesh

I'm using a custom map and everything was wroking fine at the beginning of wipe until I updated the server again a few days ago due to rust and oxide patches. Rust edit is installed properly, all the custom monument electronics are working. nav_disable is set to false, but none of my plugins along with vanilla animals are able to find any navmesh. It's like navmesh for the entire map is gone.

About to try a new map to see if that fixes things. This is so frustrating. Any help would be appreciated. 

disregard, for some reason, the update reset my nav.disable to true
