The patch does the APR-1 RWR 'fix', properly activating it on certain boats, and does nothing "operationally". When doing Saves such as you describe, are you exiting the game after the Save, and then re-starting it before trying to load the Save? You do have to exit the game if doing such. Let us know, please! If you are, then be sure you are pausing a bit after Saving to allow the game to finish its write to the hard drive, which is even more important if you have any write-caching activated in Windows, even if you are using an SSD. As usual, double-check your LAA or 4Gig Patch activation.
