I'm using the AI trade, and have oil and money stockpiled. I'm playing Germany. I've made deals with the USA over several months now totaling 20 of their oil for 6 supplies. Iran is also a big supplier so I've got 30 something surplus a day. The oil stockpile is now securely in the limit and I'm trying to sell 25 oil to South Africa for around 4.5 rare materials but that gets cancelled by the AI even though I'm still securely stockpiled to the max. Should I just shut off 'AI can cancel trades?'
