Where is the bug part? Are any of these eyes supposed to look different? As far as i know they always looked like that.

Would it be possible to completely ignore `NavMeshSetHeader` in the navmesh by relying on default values and `navmesh config` until there is a proper backwards compatible format?

I think its not needed to work out of the box with all old navmeshes. Its enough if all new generated navmeshes have a header that can be ignored except...

what would be the benefit? aren't navmeshes already in sub folders per map?
