Thanks @jamie. I would love to move the core off of the NAS, and I’ve been trying for many, many months to move the core over to a MacBookPro, but Roon core just isn’t stable on that platform (at least not with my library). I still have an open support ticket/conversation here:
But I’m curious if there’s something in running on an under-powered core that would directly contribute to Roon thinking that 6k tracks are no longer associated with a storage location. That may very will be related and would love to dig into that connection to understand the root cause.
