Are you playing the most recent version? Did you play the game and save before? Did you try modifying your save? Sorry about the questions, I'll try to identify the source of the bug.
Thank you! Do you think you could upload your save somewhere so I can run a few tests on it? It's a folder called BE_Witches_(version) located in AppData\Local.
Removing your save might fix the problem, but that might only be a temporary solution.
Either way, I'll look into it. Sorry about that :/
