Been playing around a map for awhile, then i started to notice i didn't find any dungeons what so ever, so i created a new map with a seed i knew had several Dungeons and the exact location of, but alas, they were nowhere to be found. Downgrading to 3.5.3 fixed this.

To my understanding of this you can download it through the Witchers HP to get it for other regions.
