I accidentally loaded a save file instead of saving over it.

Yeah, I know. Not my proudest moment. It’s currently a half past midnight and I was getting ready to go to bed, and instead of saving my game, I loaded a save file from god only knows when. When I realized what was happening during the loading screen, I instantly exited out of the game before it fully loaded. For context, I’m on Xbox. If anyone can let me know what will happen before I find out the hard way, I would really appreciate it. And obviously because I didn’t save, I lost over 30 minutes of switching out all my characters’ gear and buying new stuff. Just one of those days. Thanks in advance.

EDIT: I caved in and took a peak before I left for work. Everything was fine! I didn’t know if I were to load a previous save file, if it was going to delete any data beyond that since I was loading from so long ago. Thank you for the upvotes and comments :)
