My world did not properly retrofit the A Little Drama Update

I went on a bit of a hiatus and I noticed that my world did not properly retrofit the play that was added in the A Little Drama update.

The only thing that I have is this stage.

I'm missing everything else related to the stage: the carpet, the stage hands, the briar hounds setpiece.

If I need to upload my save, I would prefer dm'ing my save to a dev as I don't want my world to be available online.

Thanks.
