Game did not save

So, spoilers for the ending ahead.

Okay, so I’m playing on PlayStation 4 right now and before I go into the actual bug I love this game so please do not think I am doing this because I hate the game. I do not hate it, I think it’s amazing, and I’ve tried to ignore most of the bugs but this last one is so annoying that I have to ask about it.
So, after the Siege of Talmberg you go into the epilogue, and right before you ride off into the sunset with Hans Capon it says “Game Saved”. I didn’t think much of it until the cutscene finished and the game brought me back to the main menu. I clicked “Load Game” and the most recent save was right before the Siege of Talmberg. It’s so stupid, I lost all that progress and it’s a b***** to go back and redo the entire siege. Anyone else having the same problem? I tried to ignore the bugs, but this one cost me over an hour of progress…c’mon. A game that doesn’t save?
