I don't really understand this sentence, but like you say, it's hard to know where something went wrong in your playthrough. On the plus side, you can fix it for your latest save by
opening the Ren'Py console and manually changing variable values, or you can use
a save editor to do the same. After you save the variable changes, things should be unlocked that aren't now. Below is the code for the fantasy menus, so you can see existing values for variables and adjust them as needed. The
label fjm_eng is for Jane; the
label fsm_eng is for Sara.
