Giving it’s been a month it would probably be a good idea to release a version that has the disappearance bug fixed while continuing to develop the new content.
In general I would prioritize fixing bugs in the existing public release before developing new content, as the new content will often contain it’s own bugs that also need to be fixed, meaning there will only ever be broken public releases basically.
This way the prior build serves as a stable, reliable experience for us to play while you work on the new stuff.
