The docs ask players to edit the file by hand (github_token, feed_repo). A BOM, which an editor may add, made the file unreadable and every setting, the game folder included, fell back to its default, so the launcher showed the first run again; a typo did the same and the next save overwrote what the player wrote. The file is now read with utf-8-sig, and a file that is still no JSON is copied to launcher.json.bad and named in the log. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
