Sequencer Spawned Actor Components mark level dirty on unload

If a Sequencer Spawned Actor contains any Components such as a Point Light or Audio, the level will be marked dirty upon unloading or reloading another Sequence. Removing the Actor’s Components (and using “Save Default State” to commit the state in the Sequencer) will restore normal behavior.

There are lots of bugs with the Sequencer Spawn feature. Also “Save Default State” does not make much sense, especially when there are no keys. If not used like a double save, Sequencer just throws away any edits to the object on a regular save.
