5 years ago The issue is that updates of several required action from a scene trigger the scene to stop which in turn cancels all required actions. Commit e5ef472b542c61e8ed6355f919b235047e64f9c8 is a first attempt to fix this deadlock by making sure that a scene is only stopped once from an update to a required action and by moving the notification of changes to remote actions outside of the synchronization.
