I don't know which particular issue
dalzomo is referring to but I have an issue with the dropdown menu overlapping characters. As an example:
If you decide to save and quit after a school day while still in the classroom, the menu will drop down on top of Saiko and will register clicks on her instead of the menu. You can save because there's nothing under that, but the Quit button overlaps with her. Maybe give the menu priority over the characters.
Harem Route reported earlier that there's a missing image and error message bomb if you sleep with Mitsuko and try to have sex with her.
Not really a bug but the Thank You message that shows up when you boot the game could do well with a Settings toggle so that there'd be no need to do some end-user level file modding to disable it.
I know what it's like to be completely swamped with things. I can sympathise.
