I didn't played 0.3.2,
so I use my 0.3.1 save to play 0.4.0,
after I done all the new content,
(no more hints and all the gallery unlocked)
all other character's stats are good,
but Annabelle's stats only 40/47.
Did I miss something?
cause I don't want to play the game all over.
P.S. I didn't use any mods except the mapping one.
Have you talked to her through her open dialogs? There's only one time you can talk to her, and that's when she is eating breakfast in the kitchen at 11:00. If you ask about the MC and her, you'll gain +2 love stats, but that will only bring her total stats to (using your numbers) 42/47. So either something else was missed, or it's an old stat bug you've ran into. We've been getting a lot of reports on the stat bug, so that is likely the case here.
I've got a current v0.3.2 save
here that is a clean version and has all of the current stats correct (from last month's update) for all of the girls. You could use that to check your save and see if you've maybe missed something or just ran into the bug I mentioned.
I've informed Faerin about it, so we're looking into it.
