Bad news,
@Daedolon. I have played 0.25.2 and I have four bugs to report after an hour of gameplay.
First, the double underwear bug is still present - I saw Rin wearing two sets at school. I restored the 0.25.1 saved game; I'll try to visit her wardrobe to get rid of the bug, and get back to you.
Second, in Kumiko level 3 event, there are two images of Kumiko one over the other, one of them slightly wider than the other. The result is weird; see the attached screenshot. This continues throughout the event, at a few moments the two Kumikos wear different outfits (like, one is naked and the other in a school swimsuit). A save from just before that event is attached (renamed from .json to .txt).
Three, error messages abound in the debug.txt file. The one I can see most often is:
<0> fn:getRandomLocation([@building="onsen"][@type="street" or @type="shared" or @type="restaurant" or @type="diningroom"]) - No room found
and it appears all the time, unrelated to what I'm doing. Probably some girl's AI tries to find a way there; I can't tell who.
This error message appeared only once, when I finished talking with Emiri (level 0) at strip club's main room:
<0> fn:checkAi(waitressC) : Max loops reached. Girl location : clubA, origin : clubA, destination :
Four, if a girl is following you, you're in her room, and 11pm comes, the girl goes to bed; so far so good. However, once you move out of the bedroom, she's with you, still following you, and wide awake. I think going to sleep should break her out of the follow mode.
Update: Nope, the double underwear bug is still present, not only with Rin but with other girls as well. There's some weird interaction between the wardrobe and the girl drawing code, especially with underwear-only sets with no underwear. Maybe a new - naked - outfit should be available once the audacity allows it for a given clothing type?
