Your save file is located in your %appdata% location. It will be in LocalLow>Broussard>Oldowan. Can you send me your SavedData folder from there? I will be able to see why that happened and fix it for you. You can either send it on Discord or you can email it to admin@broussardboi.com. Do you remember what you were doing when you saved the game? Were you sleeping on a mat or in a boat or something? Trying to think of how that might've happened.
