Compatible With: Crusader Kings II 2.4.2. Checksum: YVMJ. Our hopefully much-awaited 2.4 compatibility patch! In addition to making the game not crash anymore when using 2.4, this patch fixes a few longstanding bugs, rebalances revolt risk, adds a bunch of new government types, and comes with two major new graphical improvements: new councillor models and new event pictures. Full changelog included.
