I believe this bug only applies on January 2nd. Mafia believes it is the Festival of Jarlsberg, but, today (2019-01-02), it is not.

Apparently there's an unknown mechanic for Festival of Jarlsberg? Here all the appearances that weren't on Jarlsuary 1:
Sometimes it's January 2nd, other times, it's January 1st. Other times, it doesn't appear at the start of the year at all. (or it wasn't documented?)
