Bug Report: Pieces reported as stopped when they're not

About me

This bug report is posted on behalf of the BBC

Observed Behavior

Pieces that are stopped either via stopPiecesOnLayers or stopPieceInstances don't always stop. They continue to show in the GUI as playing and the timeline objects continue to exist but the database shows them as stopped and thus they cannot be stopped without inserting another piece on the same layer.

}

For example stopping 5 layers using stopPiecesOnLayers results in core reporting the cropping of only 4 layers
