If a track contains a chain but you have a pattern selected, when you save the scene, it saves the chain in the background. This is especially frustrating when it happens on several tracks.
-> saving scenes should save whatever pattern or chain is selected.
There’s no ways to erase chains as well, so once you start using chains you have to create them for every scene.
