Storyline keeps changing my slide order

Good to see this post. I found this post by searching "storyline why my slides suddenly go out of place" and am somewhat relieved it's not just me. 

Similarly, screens will seemingly resort themselves. But it's not random.

I haven't figured out what I'm "doing wrong" yet, but I am convinced the resort or displaced slide is a consequence of a misunderstanding between me and Articulate 360.

Articulate 360 is not just selecting a random slide and placing it somewhere else in the scene.  The problem seems to originate more from a slide I had been working on a few minutes ago, or maybe a slide that was last highlighted or selected. But the consequence sure is annoying. If I could just figure out what clicks and actions bring on the resort, I'd be that much more smitten with Articulate. Instead, I'm feeling on guard, watching over my scene, trying not to overcomplicate things so I can't spot a resort too late.

Anyone feel the same way?
