Looking for the hardest map seed

[Giruv]

Hi, staying at home has make me play this game a lot again. Would love to try the hardest map seed available, before resorting to use Mod. The last one I finished is an Oassisse map with Magma Channel and Volcano, and the biggest issue on that map is there are almost no iron patch, only one swamp biome at 300+ C, and only 1 water geyser. Which make fighting the heat and developing the colony an extreme challenge.

So I would love if you can share your hardest map seed here, If possible want to get some map seed with different challenges.

Thank you!
