Are you playing on Linux, by any chance? And can you confirm that you're playing on the newest v0.308 build? I believe we've had mention of this issue before, and I also thiiiink it should be fixed on the newest version.
You will need to go back to a save before you got abducted by the moth though, in order for it to work.
If the issue still persists, or you're already running the latest version, let us know and we'll look into it.
