I'm having an issue where I have obtained a piece of intel from one hivemind, but I'm unable to use it to trade for another piece of intel in another hivemind. I'm told that I lack the needed intel ("you don't have the item."). I've double-checked that the intel I want is in the server node section of the first hivemind, and the trade is successful, and that the intel I received is in the player section of the second hivemind. I've restarted since completing the first trade, as well as retrading after restarting. I still get the "don't have the item" error.
The short answer is hivemind is incomplete and buggy. Just give it time, it will be fixed at some point.
