So I spent a long time working on a indoor walk through viewing area for any cave/den having animals. Perfect for big cats, bears, wolves. Complete with a water tank, sleeping area and mountain for more realistic look. Took about 10 hours and i tried to save it but none of the paths are saving which is kinda important because i have steps going to the water tank and up to the main viewing area. I've seen other stuff have flooring and stuff in workshop so i must be missing something when i save it as a blueprint.
