Hello, apologies for the late reply! I've been working on a new patch to fix some bugs that have been plaguing the game for a while and I was finally able to upload it today :) Unfortunately I couldn't figure out what could have caused the bug you ran into, however, there is now a way to skip straight to the ending (both main endings) by interacting with the bookshelf in Aiden's room and inputting '6890'. You will need to redownload the game and copy over your .rpgsave files (located in www>save) or alternatively replay to the part where you get to the otherworld - it should work from there. I wish I could offer a better solution but if you're still interested in experiencing the endings I hope you'll come to enjoy them anyway :)
