The brown stodala barns and the yellow garage (sarah_hasic_zbroj) have an occlusion issue when people/ai go inside of the buildings. When you look at a player that is inside of the building you can only see their gear floating. When you are inside looking out, the world disappears. When placing the buildings in the editor they appear to be fine, but when the building is actually apart of the terrain the occlusion issue occurs. https://imgur.com/a/sRDoXEF
My suggestion is to add canOcclude = 0 to the geometry and view geometry and see if the issue goes away.
