I just made a pull request to the Roll20 Github character sheet repository. This involved a single change: replacing the preview image with an updated one (file oed-roll20-front.jpg). Unfortunately, the automatic character sheet validation is reporting, "All checks have failed: There as an error with the validation check." Any ideas what that could be? <a href="https://github.com/Roll20/roll20-character-sheets/pull/11519" rel="nofollow">https://github.com/Roll20/roll20-character-sheets/pull/11519</a>
