When I finish some quests, I get the message that I got some money from the stronghold. When I look into the treasure chest in my stronghold it is empty. When I started the game at release I got money from there. When patch 1.03 came out I started a new game. I did not get money. I continued playing as patch 1.04 came out and I still do not get money. In my current game (the one I started at patch 1.03), I ignored the stronghold for some time and started improving it after I earned lots of money. During the time I did nothing about the stronghold, I got several massages that I earned money.
