Not sure if this has been bought up before or not... I had noticed it on CN:TE not sure if it is the same case on regular CN or not... But I had to active trades, another I had offered to someone that they hadn't accepted, then I had two more offers sent to me. I didn't have a harbor, so I could only have 4 trades, but it wouldn't let me accept one of the ones that was offered to me, they both said 'Limit has been reached'. When I canceled the one I had offered to someone, the other two both became available for be to accept...
