I wanted to see if anyone else has experienced this.
Yesterday as I was editing a SL 360 file, a lot of my recent edits disappeared. I ended up saving and ending because it was the end of my workday.
Today, I completed my edits and saved. Published the file to Articulate Review. Then I went back in to make a few more edits that I discovered and all of a sudden, I saw Storyline reverting the file to where it was before I started editing this morning. Luckily I was able to close the project and reopen my saved version.
This is weird.
