I'm surprised nobody's mentioned the somewhat critical bug at the post-game yet.
If you do the merchant guild owner post-game quest the dress-up system straight up breaks.
Load the save, go inside, let the scene play out -> Once you get outside the dress-up system is readonly (forever, or at least until you find an event that fixes the variable back).
No way that's by design isn't it.
It's only somewhat critical since you can just, ya know, not finish the quest. But still, I hate leaving stuff left undone regardless.
