I wonder if the Thief steals only what the character is starting with, or will he steal also the gold generated from the characters income?As dcclark wrote, it's at the start of the turn that the money is stolen. Also, assuming I've got the cards right in my head, those two buildings and the Merchant would give 3 money in addition to either normal income of 2 or a card (chosen from 2) from the pile. 1 per green building plus 1 for being the Merchant.
Say, I am a merchant with 2 gold and I have a market and a tabern. Will the thief steal 2 or 4 gold?
