In a PBEM game my opponent and I have experienced a couple of strange things:
1) The Russians have been presented the option to have two artillery units moved upfrom Paris to Warsaw;
2) After a small battle at Smolensk, in which Napolean's Grand Army HQ was involved, Napolean simply disappeared from the game. Nothing in the log about him being killed. After two more turns he hasn't shown up anywhere in recuperation. He's not in the roster anymore.
