When I input the topo and satmap, and the navmesh files to the navmesh component then “apply to prefab” and save. Why it would then remove these once I publish?

After publishing I think all is well, then I go to test in game, and the map is missing and AI are unresponsive for the most part. Then I go to check the map on tools and the navmesh is removed and the topo file and satmap as well.

It’s a very odd occurrence and quite frustrating.
