Hi, Toni, and welcome to E-Learning Heroes! ✨
I'm sorry to hear your changes haven't been saved in your Storyline project!
Let me ask you a few questions:
- Are you working from a local hard drive? We don't recommend working with files on a network drive as it can cause erratic behavior. If it's a local drive, but also syncing with a service such as OneDrive or Dropbox, it can cause a similar effect as a network drive.
- Did you receive any errors when working on your file before saving it?
- Did you experience the same behavior in multiple Storyline projects, or is this the first time this has occurred?
