I have a homebrew race that had to be completely redone and evened out. But when I search it, the old rev shows up first. Or when i click the sub race and use that to get to the main race, it directs me to the old rev. I can't figure out how to delete or deactivate the old rev. Is there a way to do that? The old rev isn't really fit for use. I don't want people to find that and think it is usable.

If you created a new version of the race, the new version should be the one that shows up when you click on it, but the old versions will still be there underneath. They don't allow published homebrew to be deleted in case someone is using it, and just trusts that creators will thoroughly test their homebrew and only upload a working version.

Also keep in mind that when you create a new version of a race with sub races, you need to recreate the subraces (as the objects remain attached the previous version of the race). This might be what is redirecting you.
