*Sorry for the title. I meant "Sea ice" not "Ice Sheet" :P

Been doing some runs on Wondrous% Sea Ice. Later on into the runs the temperature always rises above -20 C. Is this run even possible with the current ruleset?

I am currently using a seed finder to find a map with minimum temperature -32 C on the Sea ice biome. I have not found any tiles yet with these temperature settings and I do not think it exists.

If this run is completable it means you have to complete it within 64 in-game days before the temperature is >-20 C. On a tile with no resources.

Maybe I am misunderstanding the run and the rules. But I do not think it is currently doable without having dream luck.
