That happens because of lag in mp game. You can avoid this problem, if you wait few days before clicking research button again. Even if nothing seems to happen at first when you first time clicked the button, it might be that research would have started in a day or two. Patience.

You can try buying that tech from another nation. That might stop the research cyckle.
