No prob, and if you do need the file then just let me know where to find it. I'm not positive about where RenPy saves are stored. I also tried again today, just to make sure I didn't make a mistake while half asleep, and it does show the exact same ending. And because I missed mentioning this when I initially posted, I've already gotten the 100 ending for Ahmose, and as far as I know that went just fine; got the little picture of them and the text scroll. Those two are the only ones I've gotten, though.
So, I managed to finish up Sterling's storline with a dream score of 92. After watching the ending I went back and replayed from when Sadie arrives in Turkey, and managed those last few points. But the same ending played. I was able to skip through it all and didn't get a snapshot or a text scroll. I double-checked and the file I'm playing has a dream score of 100, so I'm really not sure what's going on here. Updating the game didn't help (not that I really expected it to), but I'm not sure what else I can try.
