Roon started moving my play history (100% played) from months ago into my queue. Not only that it was semi-shuffling unrelated albums in this queue it was creating. Worse than radio. Absolute chaos. Completely unlistenable. I rather suspect it has been caused by a combination of moving a large local directory to a new location combined with creating a number of SPL’s with a focus on haven’t listened to in a while. So it looks like roon is interpreting a played track as unplayed if it has been moved.
I’ve ended up completely flushing my queues and deleting all my SPL’s and starting over. Hopefully that will stabilise things.
