I recently played a multiplayer game, two humans, the rest ai. We were pretty much in step with tech in the mid game, myself and the other human, then the next time we loaded the save he had tachyon lances, jump drives and battleships. What could have possibly caused that and how can I troubleshoot it? There's pretty much no point in playing multiplayer if in the round or two where the ai is controlling your empire, someone randomly gets end game tech. Anyone seen this before?
