I was looking at my turn for one PBW game and I loaded up another game using a different mod. Instead of it asking me which empire I was and my password it seemed to go straight to the empire in the second game which had the same number as my first one without asking for a password. I tested it a few time each way and it kept doing the same. This seems to be a way to get a minor advantage because you can look at the other players empire as long as you have a game with the same player number. I apologise for the 2 people whose empires I just inadvertantly looked at. I'm off to work ina few minutes, perhaps I can email Malfador about it there.
ok. I would never do anything to cheat but having discovered it I had to test and I did discover one of the empires was next to one of my neighbours. A slight benefit, if unintentional. I'll just excuse it as payment for bug testing
