Internal error code: (562782346:687+11) assertion failed!
Duplicated a scene with nine puppets twice so I could separate them into different scenes. When I went to delete some of the puppets from the timeline, all the puppets disappeared from the timeline, but the recordings I made remained. And all nine puppets were still in the scene...couldn't delete them. I tried opening up the original scene, then opened one of the duplicate scenes--that's when I got this message
