The problem

Using the newest beta with the refactored player groups, when playing a song to a group that contains my Slimproto devices, the track progress isn't in sync. You need to pause and play the song for the track progress to correct itself. In some cases the track progress is way past the duration of the song, almost as if the counter continues even when music is paused / off.

How to reproduce

1. Have a Player Group of Slimproto devices (I do not have any other devices types to try to see if this is also problematic there)
2. Play a song
3. Play the next track
4. Observe the progress continues to count instead of resetting
5. Pause the song, see the track progress corrects itself

Was testing the theory that the track progress continues even if the song is paused and it seems possible. I had a song paused, waited a bit, pressed play and MA thinks the next track is playing but it's the same song that was paused (playing from the position it was paused at).
