In my new 1.05 (and maybe earlier cause i didnt pay attention) game, the game tells me that i get ~54 gold per turn, but in fact it only adds ~28 per turn.
Also, 2 caravans got stuck on my capital, one is an established standing on my city centre and another is a caravan unit trying to move onto there. both are from other empires. and both refuse to move, probably because they try to move to the tile where the other stands.
this basicly stops anyone (including myself) to send caravans to my capital.
here is the save game
