Civ4 was working for the most part at the lan party.
We had some interface bugs with the visa mod and Gozra's laptop had trouble syncing with the other computers. After goz moved to another computer and we restarted civ4 on the computers with the interface bug it ran fine.
As for the se5 game we really only tried two setups (one was in balance mod the other stock) but it did seem to be down right random about what players it ran the AI on.
