Anyone else have Roon just stop playing a playlist or album - un-commanded?

My ethernet is solid.. checked, and double checked it.

If you happen to have some “unknown” old device with Ethernet connection they can broadcast a lot and make problems. Like cheap remote controlled light bulbs. 
 

I assume problem isn’t present if you play a local playlist, or download it ?

Then we should probably rule out Ethernet.
