I'm currently playing the start of season 3, and i find it strange that the back button or roll back on the scroll wheel on the mouse doesn't work, is that something that can be fixed or it's by design?

This is a bug and should be fixed in the next release. Opening the developer console (Shift + o) and typing:
$ renpy.show_screen('quick_menu')
$ renpy.show_screen('relationship_toggle')
Should bring back the menus. I'm still investigating the rollback issue, though that could have something to do with the save game import (which has seen some fixes as well).
