In the Rome campaign, I was given a choice of merchants to select: Amber, Jewelry, and Wine. I selected Amber, but instead, I received a wine award. Images of selection and result screens below.UPDATE
Four turns later, I finally received a message about amber. So, maybe the wine message was about something unrelated and occurred the next turn coincidentally? Perhaps the event results should have the same name as the starting event but with a "Part 2" or something so that players know what results come from what events.
