So, I was working on some animations the day before, and I saved my file and clicked the F in the action editor next to the ones I wanted saved (There were some other animations that I didn't know how to delete), and went to bed. When I woke up the next day, I started up the file, and all of my animations were gone. Does anyone know why this is? Is there some sort of way to save your animation, or is that what the F does, even though I pressed it?
By the way, I got then back by re-loading my old save file, I just want to know why that happened. Let me know if you need any extra details. Thanks!
