Civilization – What happens to a research agreement when we go to war in Civ 5

civilization-5

I formed a research agreement with an AI in Civ 5, and when it was about halfway done he attacked me. Is that money just gone for both of us, or can we resume it somehow once I've taught him a lesson?

Investments into Research Agreements, if broken, are lost. This is why you should never go to war with your research partners if you can help it -- since you both lose.
