I would like to add that if you declare war on the person who you made the trade with then *while the trade is active* the resource is returned. -I had 2 sugars -I traded 1 sugar to Washington for 450gold over 45 turns. (Had 2, I keep 1) -When the 45 turns ends the trade doesn't end. I'm left with only 1 sugar instead of 2 -I should have 2 now to trade again but the first trade doesn't end. I can offer my last sugar to other leaders and none to Washington because he has my original still. -I can load up a save from middle of the trade, and if I declare War on Washington the trade does end and I have 2 sugars again. -However if I declare war on Washington after the 45 turns, the sugar is still lost, no return. -If needed I can provide a save from before the deal is made, middle of the deal and end of the deal. This is a pretty nasty bug which has ruined a few of my games so far, shelving the game until this one is resolved.
