Ecliptic Seasons is a new seasons mod that I personally think is absolutely fantastic, it does a lot of things really well, but there's just not integration for it with a lot of other popular mods. I think Cold Sweat should have some integration with Ecliptic Seasons if possible!

I will talk with the mod developer about adding better integration with other seasons mods. I'm implementing a system that will allow mod developers to mark their mod as a seasons mod, so Cold Sweat will load the proper configs and whatnot.

Currently, the developer of Ecliptic Seasons has to resort to mixins to achieve this, and I suspect they aren't working with the last couple versions of Cold Sweat.
