I usually just don’t use those things in combination with a fake_choice, but use a regular choice instead. Fake_choice is just too much of a hassle when combined with if’s or selectable_if’s.
The problem here lies in the
*selectable_if not (mara = "Dormouse")
line. Everything between an *if or *selectable_if command and the # needs to be encased within parentheses. Even the not.
This should work:
*selectable_if (not (mara = "Dormouse"))
