When a download fails because MakerWorld refused (or is missing) the auth token, the error carries reason makerworld_token. The import and "Download files from source" then open an "Update your MakerWorld token" prompt with steps to copy the token cookie; saving it retries the download straight away and says if MakerWorld still refuses it. A missing FlareSolverr URL is reported separately, since a token alone won't help. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
