Really enjoyed the update! Nice big chunk of story!
There's a bug with the main quest. You're able to talk to Sayori on the bridge in the Morning before other main story stuff happens. I was initially super confused thinking I'd forgotten or missed some story, but I had to instead wait until the Afternoon and go to the training grounds first.
Also, did Keiko's affection get reset to 0 at some point? I thought I had more than that from all the events and stuff. Same with Fumiko, hers seems low too.
