Found a bug.To all of you who ask for help - sorry I can't help. I need to concentrate my support for my Patreon's and work on next release 5_0.
If you are stuck - don't use scroll or tab Read dialogues and follow the daily routines. If you do so - the game is easy.
I might be wrong, but if you raise her "shy" too fast, you cant trigger the "frozenglass" events which prevents release2_4 flag from setting and stopping all further progression.
line 642 in bathroom bypasses line 655 which is the only place to progress with frozenglass.
Perhaps it worked as intended in earlier releases, but now it's broken.
Hope it helps !
