Static Mesh Not Updating Navmesh
Steps to reproduce.
If you try importing another static mesh and this time TICK Auto Generate Collisions, then it works fine. So the bug seems to be that manually adding collision to a static mesh requires the editor to be restarted before the navmesh will recognise the collision geometry.

I have been able to reproduce the issue of the NavMesh not updating unless you restart the editor, and have entered a bug report, UE-23125. Thank you for your report.
Have a great day,

A fix for that would be much appreciated now. It took me 2 days to understand why my navmesh was not working, before I understand I have to restart unreal to make it work.
