Well, this isn't a huge bug, but I figured I'd report it anyways.
(This topic contains EP8 spoilers. Be warned.)
In Bernkastel's game in EP8, when you want to check the purple truth by character and check Nanjo's, his graphic changes to the original version whenever you press the "Next" button.
When you first check his purple truths, his graphic appears as normal, as it is supposed to.
However, once you press the "Next" button, his graphic changes to the original version, and it won't change back unless you select another character's purple truths.
Pressing the "Back" button still leaves him with his original graphic, as can be seen by this final screenshot.
I know it's a really small thing, but I wanted to report it anyway, just to let it be known in case you guys upload a patch with fixes later (or if you ever get to editing the graphics for the music boxes, for example, altho it isn't needed, of course).
EDIT: oh, this only applies to Nanjo, by the way. All of the cousins (except for Maria) also have two pages of purple truths, but nevertheless, pressing Next or Back does not affect their graphics.
