Aah I get it now. I'll implement a fix for this. Thanks for pointing this out to me :)
Thats a new one. Well anyways I've fixed it, and I'll be uploading a patched version asap. Thank you for the bug report
Edit: a new version is now available here on itch. You just download that and put your old save files into the new game directory (v 4.3) and you can keep playing where you left off.
