The leader scene fix for civs above 22 doesn't work for me, or well it partially does.. it works for official civs only, they have the 2d static screen, but custom civs show some painting of a garden or something, probably a wonder splash page, but I can't remember which one.. is it common/supposed to be like that, or am I doing something wrong?
It would be impossible the add 1 fix for all custom made civs (since the leader load screen has to lead to a specific location) i.e. the leader fix works for standard civs. There's an easy workaround this though: just select all custom civs you want in first, and make sure any civ above the 22 civ limit is a standard civ.
