I've so far obtained endings 1, 2, 3, 4, 5, 6, 7, 8, 10, and 11, and special endings 13, 15, 17, and 18
while i wont spoil too much (unless asked), what i will say is that even a slight change in choices or a difference in choice orders can lead to new endings. I have to give it to DG, this is an impressive branching-choices-esque game that was well worth the wait.
I mentioned encountering something similar when doing her lessons in an earlier post, though I haven't encountered the sleeping one yet. I think it has to do with certain choices and/or choice orders (in regards to whether you encounter them or not). But I think the problem is being caused either by an error in the coding, mislabeling of necessary files, or something along those lines.
