Another bug:
When a girl gets raped, it can happen that the rapist gives her a tip.
Edit:
And another one, sorry for finding more work for you.
I have girls with incomplete fetish list under "more details". For example Hakurei Reimu has the trait cool person but the fetish cool isn't in her fetish categories. Asahina Mikuru, Akizuki Ritsuko and some random girls had this problem, too.
I don't know if it is a coincidence, but every time a fetish is missing, the linked trait is the first one in the trait list.
