@simsplayer818 Regarding your second suggestion, the number next to my gamertag is 82.8 MB, and the number for reserved space is 1.0 GB. I think I only have about 5-6 save files, so I don't think that's the issue, but I also have a third save data with my brother's saves on it. Would that be causing any issues hypothetically? My brother can't access those saves and since I live 3 hours away from him we haven't had the time to troubleshoot it together, so I don't know what's up on his end, just figured I'd mention it.
Thank you for all your help, hope this is able to be resolved soon!
