They keep saying "I'm tired." "Just a little bit longer" I am not sure if this is a bug or smth
Oh sorry, mm. Sorry I assumed you were stuck at Divine, I mixed up their names because of early dev stuff.
You should be able to progress by going to the right of Lumi actually. There are things that take place to the right of the library upstairs if you go that way. It should be fairly straightforward unless something isn't working. Can you not go to the next room? What do you mean by stuck?
