There are instances where you can't have sex because "you cant find condoms" even if you have them in the inventory. Then there are cases where pregnant women demand them because they don't want to get pregnant. Also you can get Samantha pregnant (earlier than designd[?] with hung-trait) and game seems to treat like she doesn't know it, even if it visually very obvious. Are these bugs?
Also, there seems to be math issue various values. Like you get -2 affection but the number goes down by 3 and that sort of things.
