King vassal of a duke

[artfox]

In the William the Conqueror scenario the king of Sweden is a vassal of the duke of Uppland even though he's at war with him which seems... odd. When I tried to click on the king of Swedens portrait in the vassal subfolder the game crashed.

Sorry, I can't reproduce it in the usual William the Conqueror scenario. Erik 'the Hethen' has 9 vassals, none of them Erik II of Sweden. Could you please attach a save where it happens?

on around 11XX the king of Jerusalem is the vessel of the duke of eddesa

I would need a save to this issue as well. In the future please create a new thread instead of adding your issue to an existing one. This is another issue although it is quite similar.
