Oh! I'm so sorry! I never realized, when the App Store said version 1.01 has been updated with "Fix rare random issue with the weekly schedule," I assumed it meant the game sometimes crashed when someone would edit their schedule. I tried playing one of the routes and you were correct. The problem is gone now. Thank you for the fast reply!
I'm playing as Anne and doing Dominic's route but some of the week days didn't happen they were, week 12 Saturday event, week 14 Friday event, week 17 Wednesday event, week 18 Tuesday event and week 21 Monday event. I don't know if i did some thing wrong.
