how do you unpatch the game?

since the last patch ive had nothing but problems with steam not connecting or the game crashing after a few turns how do i unpatch to a more stable patch?
also how do i stop steam autopatching the game?

im sick of beta patches being released that ar eunstable and not having any choice but to use them

I don’t know of any way to un-patch the game.

As to avoiding more patches you have to go to steam and play in off-line mode. You will receive no patches, etc until you go back to online mode.
