Not sure if this is a 1.8 bug/feature/quirk, but Roon Radio always seems to go for a streamed version of a track (that’s not a library version) even when that track is in my local library at the exact same file resolution.
Not a huge deal, but it means my track stats and play counts aren’t updated. 
I don’t want to restrict to local only. The mixture I had in 1.7 was good.
