That's intended. The area past the skunk girl area is not yet developed, so it instead returns you to the beginning area. If you end up in a pitch black room, that's a bug that's been found and reported many times in the past.
The second part i already knew, since i was one of those people who reported it
Yes, the specifications are to go back to the first area because it's imcomplete. Thanks for explaining that!🤝
