Research keeps repeating itself

Playing a 2-player online game as France, the Portuguese player keeps researching the same tech over and over again (an economic tech), and each time he finishes researching it, he is forced to research it again. What is the problem?

Its a known bug - which doesn't help you I know but try reducing the game speed (or lag if you can improve connection).
