For doggy variation i found a bug. When i set her variation 2 nude, in the clymax she become into variation 1 on clothes, and also you mention a 'malfunction' but i can't reach or find that scene. :v
I think malfunctioning is just when you keep repeating her overheated Doggy scene until she's completely passed out on the bed with her mouth open and eyes half closed. This puts Ako out of commission for the rest of the day.
