(Update: Figured it out, but am leaving this here in case someone else runs into something)

Greetings mods!

I'm looking for some pointers as to what might be wrong with my subclass build.  It isn't quite ready to publish, I still want to do some playtesting, but I'd like to know ahead of time what I need to cut so that I can playtest it within the guidelines.

I mapped everything to the appropriate Bard levels.  There are no spells found outside of the basic rules/SRD.

Any pointers?

Thanks in advance!

I’m not a mod, so I cannot see that. What I can tell you is that if you did everything right, then all that’s left to do is re-save the entire homebrew using the main “SAVE CHANGES” button under basic Information. That’s the only time it rechecks those compliances.

Yeah, I've hit that a couple times.

I also dug deep, deep into the forums here to find anything that I might have done wrong.

Found it.

I had made a Homebrewed Version of "Detect Thoughts" once before.

I accidentally selected it in the class features.

I had cleared it and saved.

But I hadn't replaced it with the proper one (I had, but it didn't actually save.)
