Scene view objects reorder after play mode in hierarchy

As described in the image below. I have three objects… Toolkit Loader, Debug, HeroCreature. I want them to remain in that order when not in play mode.

If I play and exit, they’re fine. Toolkit Loader is destroyed in the scene after play mode starts, and comes back. Normally the hierarchy is constant, and everything is fine.

If I drag something (Ratkin Slave in this screen shot) and drop it in scene view, it shows up in the second slot. (Is that normal? I didn’t drop it in the hierarchy, I dropped it in the scene view. Kind of strange to go into the second slot. But, it’s fine.)

When I enter play mode, toolkit loader destroys itself during awake, which is fine, but then HeroCreature pops up above Debug. (WHY? BUG?)

Then, when I exit play mode, HeroCreature remains above Debug object. (WHY? BUG?)

Thanks.

Anyone else experienced this?

I guess I’ll try to reproduce it in a small project and submit a bug to unity (if they still have that option through the editor.)
