Interactions are a handy way to break up content. But if you’re looking to branch out from the typical tabs or accordion approaches, try this click-and-reveal instead.
This interaction makes adul...
Are you copying the Slide from one project to another, with two Storyline windows open simultaneously? Or are you using the import feature, found under File > Import? If you are importing, which insert option did you select?
Choosing 'Current scene' adds the newly imported content as the final Slide in the current Scene you've built out so far. Is there a chance you've selected 'New scene'? Doing so will place the new Slide into it's own scene, and automatically switch the Scene drop-down menu to that newly imported content. This may give the impression that other Slides are now missing. However, they are still in the project, just within a separate Scene. Clicking 'Story View' will give you an overview of all Slides/Scenes within that project file.
If you're still having trouble, seeing a screen recording of the behavior can help us troubleshoot this better. Feel free to share that here in the discussion or privately through a support case.
