How do forks stay up to date?

Your fork picks up parent changes automatically — for any entity you haven't edited yourself. If the parent author publishes a new feat, your fork shows it. If they fix a typo on an existing feat, your fork shows the fix. If they remove a feat, it disappears from your fork — unless one of your characters has it picked, in which case the entity stays put.

Once you edit an entity in your fork, that entity becomes yours. Parent changes to that specific entity stop reaching you — your version takes over. Other entities you haven't touched keep updating from the parent as before.

This per-entity behavior protects your customizations. If you've rebalanced Power Attack to fit your campaign, the parent's next update won't silently overwrite your changes.

To re-pull the parent's update onto an entity you've already edited, delete your local copy (the inherited version returns, but your changes are lost) or manually re-apply the parent's change.
