Seems like the playground rewrite disabled the ability to use the full URL pattern. @Deltakosh - are there any new rewrites we need to configure?
In the meantime you can use the hashcode format:
[https://www.babylonjs-playground.com/#F41V6N#32](https://www.babylonjs-playground.com/#F41V6N#32) and
[Babylon.js Playground](https://playground.babylonjs.com/#98TM63)

The playground is deployed the same way as before so if it was working it should still work
And if it does not we have a bug:)
