In my game the first 3 swamp locations I visited didn't have any crypts. Then i googled and learned about that distance-from-edge requirement, went to a larger swamp and I got enough iron to craft everything, upgrade it entirely, and fill 2 reinforced chests with 'extra' iron out of just that one swamp's crypts.


They really don't need to change anything, there's already a ton of iron out there, you just gotta find it.

So you found 1000 iron in one swamp? This is roughly the amount you need to build everything requiring iron in the game.

I'm on the side of the OP. Yes of course small, stretched out swamps won't have any crypt, but even big ones sometimes don't have any either. The algorithm to generate crypts has always felt wonky to me. It creates some big clusters and leave some large swamps completely empty.

Considering how important iron is it wouldn't hurt to tweak that a tad. And on the same note, the last update changing the world limit on crypts from 200+ to a bit more than 100 was dumb.
