In my attempt to get all the endings I've been over the way three times now, and each time I simply cannot get the postscript to the ending in which Rhue mentions "so you do paintings" (and so on). I've looked at the painting by Kloe in Ep2 every single time, and not once have I gotten the correct ending to work in episode 6. Rather, the ending fades out earlier than it should (instead of rhue saying "I .... can't" it fades out on the I ...) and for some reason, Strata appears in part 1 of this scene, but never comments (and I'm fairly sure that was removed from the game, Strata was never meant to appear).
So I guess I've got two bugs at work here, or I've edited the map so that I've turned the switch off somewhere, I have no idea which. I am not sure if this is actually an issue with my Save being bugged or somesuch, however. (This is on version 1.1 of Ep6, because I can't find out if there's anything more recent). I'll upload the save if anyone believes they need it to pin the error down.
