As title says, I don't know if Im just that unlucky, but thus far none of the swamp biomes had any single sunken crypt, and to make it worse, each of them seem to border a plain biome which makes them super deadly. Im 40+ hours in the game and have yet to smelt my first iron bar.

I was wondering if anyone would be willing to share their world seed with a screenshot of a swamp with a few crypts in them. I don't like to resort to that kind of method, but as a solo player who doesnt have anyone to play with, these trips to a new island, building an outpost, scouring the whole swamp while dodging deathsquitos is not really fun anymore. I've lost dozen of levels in these expeditions dying to the archers and it hurts that much more when i realized it was for naught as no crypt could be found.
