Disable Malwarebytes, Norton, Avast
Just gonna leave this pinned here as a friendly reminder: Malwarebytes and Norton both corrupt your save files in Brigand and ruin the game. Disabling them or adding exceptions will fix the problem. Malwarebytes worked with me a while back and temporarily fixed the issue, but then the issue came back and I don't feel like doing it again. There are probably other anti-virus programs that fuck up your saves, too, I assume.
