After purchasing all the DLCs for Fantasy General 2, I encountered some reading errors in my game save files (as shown in the picture). Before and after the main story mission involving a battle between barbarians and lizards on a sunken ship, almost all save files except for the first round fail to load. I have checked the game integrity and even reinstalled the game, but there has been no improvement. I really enjoy this game and have played it for 129 hours, but not being able to load game saves sometimes frustrates me. I hope you can help me.
I am unable to share images. When accessing save files in the game, I am directed to a map where the entire area is shrouded in fog, obscuring both my team and enemies. I am also unable to perform any actions, and can only choose to restart the game from the beginning.
