I'm not into the beta expansion.  I'm still having enough problems without adding to them.  I was just playing a game where I conquered 3 Yithril cities in a short time.  I then wanted to send out trade caravans from the conqured cities.  The icon was grayed out, so I assumed that the caravans were still active somewhere, but I looked and couldn't find them.  Then I went to the city state window for each city, and it said there were 3.0 caravans available for each of the cities, obviously wrong as you can only have 1 per city.  Also on that page where you are supposed to have a description of where a caravan originates and where it is going to, there was nothing, other than saying there were 3 caravans available.  Any ideas?
