I just came across this because I have a theme with panel styles that render slightly different depending on route. One of the categories on the client instance resolves as `discovery.categoryNone`. Would someone know why this happens?

I think that’s the default list filter? `https://talk.fission.codes/categories.json` has it set to none in all of them. `https://talk.fission.codes/c/apps/11/none` has it too. But some others don’t.

This isn’t much of an answer. 🤷

Ah ok! It’s the default list filter setting to not show topics from subcategories:

Didn’t come across that before and couldn’t make sense of what’s happening there. Thanks for the nudge @pfaffman!
