From the mount log, it seems a bit tough to tell if it's skipping over it or not.
Can you just do a rclone lsd OneDrive: -vv and share the output?
I think I see the spot and it might be .hidden in your log, but that might not be it either.
I wonder if the links are actually presented to the API. You are connected to your OneDrive and you were at a Sharepoint site and hit 'add to my onedrive' right?
