The trading post shows the icon and the describtion of a full storage even though there are no items in there.
This possibly has something to do with the gold transfer from trading psot to storage. After emptying all of my gold from the trading post to the safe house, the actually is no gold in my safe house even though the trading post menu shows that there is 0 gold stored. I have the gold, i can use it to build/buy and it is displayed correctly in the top right corner but its not visible in any storage.
