thank the thing is i know why it's entirely because i renamed/shuffled around some of the music files but when i was updating the music calls i FORGOT some of them... thank you so much for your help and your detailed reports....!!
You're welcome, glad my bug reports can be of help! Also just encountered another bug, in Bern's normal route's post-credit scene, when you're about to show him "your ideal man"(I presume a photo of Bern), I received the error "Failed to Load: img/animations/Flash.png" preventing me from finishing the scene.
