Rewrote a chapter with a single scene. With the context set to that chapter, I clicked on 'archive scene' in the 3-dot menu. A blank screen popup stated there's no story text and I needed to add an 'initial' scene (scary message but I knew it meant the chapter text and not the novel was missing). Clicked on the Add Scene button multiple times and nothing happened (Edit: It added 2 new acts with a single empty chapter at the end of the outline). Went into Plan and the empty chapter is still in the outline. Clicked on Add Scene button there and it worked fine.
