So when I play any Dig Deep map, I have this issue where I get a lot of the same blueprint, I seem to always get the Goldpieces blueprint, which is a Gold Block -> Gold Pieces. I also have the same issue with Wisdom Scrolls, I've gotten the same one every time, with it saying, "Myths are clues to the spiritual potentialities of the human life." I haven't gotten a different scroll besides that one, and I have 6 of them so far.
Also, just to point this out, I found the Iron, Steel Pickaxe, and Greenstone Gold Hatchet all on the surface, which I don't really think is supposed to happen.
Here's the map with more proof of the bug. The crate on the right side on the top has all the repeat blueprints, the one of the left has all the scrolls:
