Well, a possible one, anyway, I'm bringing this up in our private forum, and directing the mods to it. The exploit was found after I noticed a possible abuse of it by Cavs (note: Cavs may not have done this, but I can't think of anything else that it plausibly could have been). An hour after Cavs ended their turn, their score decreased by 6 points. No other player was logged in at this point, and MS had not ended their turn. The former means that it could not have been a city gift (as there was no one to accept the deal, and there was no corresponding score increase), and it could not have been a barb related issue (as MS had not ended their turn, and all barb moves occur after MS hit enter). Ronnie set up a test pitboss game for us to test this in, and showed that it is possible for a team to slave after they hit end turn, which is an exploit as explained below: When you hit enter your and are allocated to your city (with that pop point) so if you after you hit enter you then slave away that pop point...you essentially get free , and This is only possible in sequential pitboss because only in this game format is it possible to slave after the food et al is calculated; PBEM and SP, ending turn finishes all possible actions until the next turn starts, and in simultaneous turns the food et al is not calculated until turn rollover, so there is no free , or So the game needs to be stopped and reloaded to Cavs turn so they can replay without the slave.
