I didn’t figure it out, I’m pretty sure it won’t have solved itself, so I would be pretty confident there’s still something wrong in there. I haven’t read any code or looked any deeper. As I say, for most purposes it’s only of casual interest and would just defer a badge or promotion for a week or so. But my comment about L3 demotion stands.
It would bother me, I think, if I had any responsibility for a codebase which can’t count! It might even interest me to look into it, but not everyone is made that way.
The queries I did could readily be done on other forums - not on the sandbox, I suppose, as it isn’t long-lived.
