I actually don't think its the save that's breaking the AI, because you can save the game, then right after select the load option to reload the save, the game will still work, its only until the game is restarted (or loaded from the main menu) that the ai breaks, so either something on the main menu is breaking the game or its something not being loaded properly that only gets loaded when starting a new game.
A temporary workaround I found is first start a new game skip all the intro and dialogs (Start - X) and get to the map then press start -> Data -> load then load your previous game where the AI was broken before, the AI should work again now and you can continue on.
