Short description of error
Deleting keyframe in node group makes a zombie action data block when the node had an action.
Exact steps for others to reproduce the error
- Add a node (e.g. Material node)
- Insert a keyframe for a parameter of the node (In this operation, "Shader NodetreeAction" is added)
- Make a group include the node (In this operation, "Shader NodetreeAction.001" is added)
- Delete the keyframe in the group
Then go Outliner and select Datablock view, you will see two action datablocks, "Shader NodetreeAction" and "Shader NodetreeAction.001". Latter has no users (so it will be deleted when save the file), but former has one user that can't be delete.
Why the original action remains and can we delete it?
