OK found it, in Lawrence's neutral ending there wasn't the usual "notification", going to add it to next update. Remember that the bonus stats epilogues only show for the happy and sad/bad endings, not the neutral ones
Just got the Sad Ending 2 with Aaron, but also got the Big Blue Eyes ending at the same time, which seemed a little at odds with each other I don't have a save game, sorry. But my Romance and Diligence stats were high if that helps?
Uhm... :D that doesn't sound good indeed. I checked the code and you're right, you should have got the skill ending, but the normal/sad one, called "Can We Be Friends?". I have fixed this now, on next update it should work fine. I think will probably do it tomorrow morning (8-9h from now).
