I genuinely have no idea what went wrong and I'm in a frenzied panic. No error happened. I saved and closed. No pop up nothing. I saved it. Did that anxious thing where you try to save twice and it's grayed out the second time. Not 10 minutes later did I figure I wanted to add something to the graphic and it's gone like nothing happened. I still have illustrator up from this session, but I'm completely clueless. I'm trying to figure out what happened or if I can get a save history transcript or something. Whatever back end data there is available. Anything helps.
Can't seem to edit (or delete) this post but I figured out what happened. I saved over it with another file of the same name. I doubt there's a way to get to the version I want to keep, but if anyone can give some advice, it would be deeply appreciated.
