my guess is you have the game befor diary but that doesnt make sense due to loading screen i see so all ik is that it has problem loading dairy data you can try to clear cache or at worse clear storage of game itself an try enter save again(or 3rd try reinstall game)
spreadsheet here but each tlsq is based on year so you need to look for specific year tlsq is in .
I checked it. It said "5 stars = 5 HP" but it didn't clarify that it was possible to earn HP depending on the amount of stars you got. So I assumed that I was good as long as I didn't get the full 5 stars, but I still got 3 house points even though I only did 4 stars.
Yes, you earn points in the became a prefect tlsq
