I have that with some changes in code , requirement for that is
if inventory.has_item(jacky_bikini_01) (= True) ... other are libido and so on
But if I force the variable (with console) and save and reload the game , the variable changed again to false.
In script.rpy I removed two lines
label after_load_000001:
# python:
# jacky_bikini_01 = NewItem("Jacky's bikini 01", outfit=True, image="images/interface_images/inventory_
and finally worked for event 18.
I can't post a save because without patch doesn't work .... and it is a solution that can break the game.
Better ask to the author
