After the fight with Mardracht, I no longer have the option to Save or Load a game. Those options are grayed out. I have tried changing areas, long rested, etc., and the options to save or load a game stay grayed out.
If I quit the game and go back to the main menu, the options to "Continue" and "Load" a game are both grayed out, and hovering my mouse over them tells me that there are no valid save games.
But when I exit the game and restart, I have my full list of saved games, and can load any of them and play. But as soon as I fight Mardracht (I have done this fight 8 or 9 times now), the bug to not be able to save is back.
At this point I am stuck and can not continue the game
