Symmetric Earth with 90 obliquity and 0.1 eccentricity (Patreon)

Finally. My experiment with trying to get it to automatically find the warmest stable ice belt climate never really worked, so I ultimately just had it balance at -5 C, which seems to be close to that point anyway (this isn't the only thing I've been doing this whole time, I've also been doing some runs of Teacup Ae again to get climate inputs to that ice sheet model).
