Saved games will not work after updating...... :/   But chin up you get a patch update and it makes the headache of starting your long term game all over even better

Read the patch notes? this is underlined in it. They can't make it any clearer can they?? A neon sign in your front yard perhaps? Just so ya know though, every patch for sins does this, so next time you will know to delete those save games first, or finish them then patch up.

NOTE: THIS UPDATE WILL INVALIDATE YOUR EXISTING SAVE GAMES AND REPLAYS.

^Yes, right click the game and select 'View History'.
