I don't know if this has already been dealt with, but here’s my situation. My brother and I are both running version 2.01 while playing LAN. Randomly, his research doesn't progress and becomes stuck. It still drains research points and the progress bar gets to 100%, however, it gets stuck in a loop and repeats the research process. All of our efforts to stop this problem have been unsuccessful. I don't know if this information matters, but he was Mexico and researching Iron Mussel Loading Artillery. Any help is appreciated.
