I use trades to balance my resources and unless I am missing something there is a huge problem with trades.
I have found several deals in trades that I sent a request for that have not been accepted or declined. But my goods have been taken out of my warehouse, so I cannot access them. Yet there does not seem to be any mechanic that cancels old trades after a set amount of time, nor can I see or cancel my trade requests.
There needs to be a way to see your outstanding trade request and cancel them after a certain time.
