The problem

Whenever I "turn off" my Snapcast Playergroup, an error pops up and is also mirrored in the MA log
'set' object has no attribute 'set'
It doesn't seem to break anything major, but during testing I had some weird behaviors with one or both of the group joined players disappearing until MA restart.

How to reproduce

Add two Snapcast players
Add both players to a Snapcast type playergroup
Play media to playergroup
"Turn off" playergroup

Music Providers

Seemingly unrelated to music providers (has occured at least with local disk, tune-in, radiobrowser, jellyfin)
