I am no longer able to overwrite old manual save files. I get a message saying "There is not enough free space in system storage", and I am directed to delete unused applications.

The thing is, I have more than enough free space, over 300 gb. I can still quicksave, autosave and even create new saves, but I just cannot overwrite old save files.

I guess I could simply just create new save files all the time, then use the save data manager to manually delete older saves... But I would still be grateful for any information on this bug, and how to overcome it.

Thanks!
