So, i don't know if it's known problem, but i was selling my 3 slaves i captured in slave raid.. Sold two of them but when i tried to take the third one on the market, after clicking "time for business" nothing happened, slave trading event didn't popup. Now it seems my ruler got selling slaves event and i can't click "sell slave" anymore. I waited couple of years but nothing.. Any fix for that or ist that supposed to take time?
