Dude I had The same issue three times playing HP 1-4 years on ps4. I searched for solutions and maybe if you try to save with a USB stick solve your problem. I tried to back up and it doesn't worked. I going to buy a USB stick and see if it rlly works
There was a very hot girl named Mica who kind of hit on me in the uni, but I didn't follow through because she was too young and I already had a "don't date girls younger than 20 /21" at the time.
