1. Every time when having sex, unless roles are switched (through usage of magic eggplant), after 1-3 frictions big amounts of smoke appear on girl (heat doesn't matter) and blue health bar starts to quickly deplete (like if there was 10-20 consecutive frictions, one after another). Speed of this depletion is constant, badges won't affect it. UPD: Made several tests. Looks like this bug happens only with Zaria, Kinwa and Oriana.
2. Zaria lost her virginity during heat sex. Immediately after, she lost her virginity again (no white rose was used) after usual sex.
3. Maybe a bug: Milking rooms give energy even when empty. Empty swamp room probably gives a lilypad too.
4. Maybe a bug: Drills and villages give you resources every time when you move. It makes possible abusing flags and milk rooms to multiply harvest up to x14 times.
5. It is possible to "take" main character in your squad. So, there's two main characters in your squad. More HP and ATK, less abilities.
