So, when I enter the game, I click my way to hotseat campaign. When, after clicking multiplayer and then the hotseat button, it simply skips to choosing factions for the base mod campaign. Furthermore, I know that the unofficial patch is installed as I can access, and have played part of a campaign, of a single player campaign with your version of the Oblivion crisis. With multiplayer, it simply bypasses being able to choose what campaign I, and my friends, play.
