Hi,
The save now screen even says to rollback and NOT to save on it, or my reading comprehension has gone wonky.
I may be wrong, but at lease my code "hack" allowed me to load my game and finish this update.
I always save at least 2 screens before the ending save now screen, and at every important (to me) in game choice.
I do this for most games, because Players never know where Devs will pickup the save in the next update, but usually saving 2 screens before the end, those scenes are still in the next update.
This is not a perfect system for save compatibility *crossing-fingers*, but Players have to do what they have to do, so we don't lose all the time we've put into playing the game.
