I think the infringement email is random. I have all game slots running with a variety of jobs and they've all gotten hit with that email. It's frustrating and doesn't add to the experience. While we're at it that earthquake event is also VERY annoying. Just when I had all my floors fixed after 3 generartions mind you because the store rarely carries the floor repair kit, bang! Earthquake ruined all my floors again. Hate that earthquake. Now I buy the floor kit even if my floors are fixed and keep it around in case.
