Updated to Build 200 last night. Since then I have had 2 crashes and the auto detection of new music is very very slow. When it crashed the first time and did a rescan, no artists would display in Roon though I could search on one and actually go to the specific artist page. But the artists page was empty.
Additionally, auto detect of new music is not working either. Previously, in my system new music that I saved to my NAS would almost show up instananeously in Roon. Several restarts of Roonserver has not fixed this.
