Do you have story_nutaku_kamihime_6419.rpy in scenario folder?
I don't. The problem should be about one of the tools. I will redo everything with a fresh player and check what happen (just before closing the .bat). I'll keep you informed.
I did a test (with the nutaku player), it worked just fine, but it seems to not work that well when I update the nutaku/dmm player... Do you have any idea what might cause my issue?
