I bought Fallout 4 this weekend and started playing last night. Everything went fine until I started it up and noticed that the last time I tried to save before turning it off for the night. Luckily, the Auto-saves and Quicksaves still work so I only lost about 10 minutes of gameplay. However, the manual save doesn't work.

Whenever I try to save, it asks if I want to overwrite the old save and I say yes, It pops up with the progress bar. That progress bar stays at 0% and It closes the menu as if it did save, but it doesn't actually overwrite the old save.
