Publishing fails with "scene check failed"

Luduvo's server is turning down your publish. It started with build 45 and other creators have it too, so it's probably not something you did.

What you see

Studio shows a Publish Failed popup: HTTP 500: {"error":"scene check failed"}. Uploading a world file on the website says scene check failed as well.

Who's affected

Creators publishing from Studio, or uploading a world file on the website, since build 45 came out on 26 Sep.

Why it happens

Not known yet. HTTP 500 is a server error, which usually means something broke on Luduvo's side rather than yours. unconfirmed

What to do

1. Save your project in Studio so nothing is lost.
2. Try publishing again after the next Luduvo update.
3. Follow the thread for news. Scene check failed when trying to publish a game

Don't bother with

• Rebuilding your project from scratch. Several creators started getting this on the same day.

Status

Still open as of build 45.
