v10 savegame culture and religion broken, and tournament betting reduced

[jones]

All of my v10 savegames seem broken as of v10.1 (steam workshop).

When checking Character/Story it always says "You are from the westerlands..." for both culture and religion.
I cannot convert religion at any shrine, there is simply no option.
My savegame religion was free folk/rhollor, when going to RHollor I have the option to ask if anyone will join, but then I get an error saying I'm the wrong religion.
I don't have a v10 savegame with master of whipsperers to test changing culture.

My savegames also all have different game options such as they are now all difficulty Impossible (there were Full Realism) and Disable Scenic Menu is unchecked (my savegames all had it checked).

Also, tournaments now default to simple and betting amounts are half what they used to be.
I now have to change the setting to expert at my next tourney, and can only be 250 max, meaning earnings from tournaments are now capped under 10k, making the grind is this game much worse.

Is there a way to revert the steam workshop mod to v10?
