Did you delete save in game ? I have the same issue and when I delete save while in game, I can't replace the deleted save unless I quit to main menu and reload the game. In total, the max save I can have is 205 including autosave, mission save and chapter save. While talking about autosave, I tought 9 was the max but I can have up to 10. Is that normal ?
Mine was persistent beyond going back to the main menu, but otherwise similar.
I'm sorry for you. I tried really hard to figure that bug out. It's game breaker for me and it is sad because I absolutely adore this game. Seems like I got lucky. 205 save is still a lot considering we only had 30 per career in ME3. Just have to delete some more now
