It seems like some blair events (birthday and love book) are for the trap version only.
The reason I say this, is because in the code, there are two different stats for the female and trap version (MyCharacterStats["blair"]["Affection"] for
TRAP, MyCharacterStats["blair_f"]["Affection"] for
FEMALE), both of those events are gated behind MyCharacterStats["blair"]["Affection"], meaning that the female version of blair will be
UNABLE TO VIEW THOSE EVENTS.
I have included a small fix to rectify this for people who have
SET BLAIR TO FEMALE, although it may end up with things being a bit funny due to blair technically being a trap in those scenes, but at least you can now view those events without manually setting blair's affection to the required values. Thanks to
SnowyFrost for pointing out that Blair's 4 affection points event is split between trap and female
The other events don't require them, because those checks are already included in the hotfix.
