I'm assuming this has to do with the switch to https. Whenever I click on the nation link on the forums, (Here and my alliance forums), it directs me to the PW login page, where I have to login again, despite already having a tab open, and then when I login, it takes me back to my nation page. Long story short: Nation links in forums are broken.
Also, all of this: https://politicsandwar.com/forums/index.php?/topic/2898-whenever-i-trade/
