Hello! I've just released an update which I believe should fix your issue!

I've changed where the data is being preloaded from which should remove the need for Scene_Title and hopefully fix your issue.

Also be sure that you're following the steps from the ChildMap section. You can change the tag to anything, a * or a - or whatever. If you don't follow that step you might get that same kind of error

Let me know how it goes!
