Hello; I clicked Create a New Version of a homebrew subclass so I could clarify some wording and change the title so all of the homebrew subclasses I made for my setting clump together alphabetically. But, now that I clicked Create New Version, that version is deemed to "not have the necessary class features with the correct required levels." Nothing should have changed in the new version; is there a known fix to this?

EDIT: Realized a link would help (https://www.dndbeyond.com/classes/fighter/subclass/507238/edit)

Fighters require a level 5 feature to be able to be published. I have no idea why because we've not gotten a single official word about this - whether it's intentional or a bug or what.

Huh. Thanks! That fixed it. I followed the levels with required features from here:

So I never thought to try adding features at other levels! Problem solved. I just made a Placeholder Feature and checked hide on sheet and in builder.
