I believe it must be an installation error, I tested it a few times and didn't get this error, watch the video below:

Which character were you in this bug?
I was playing as Marina, and I think the bug with the female villager was because I was in the allay next to the basement hatch but I'm still getting the ratkin gang bug. I don't think it's something to do with installation because i made a copy of the base game and followed the installation direction and still had the door lock and ratkin bug
