Summer Insulation seems to be broken.

@FurryEskimo

I never liked how Klei referred to these downsides as "More susceptible to heat/freezing". Because that's not really what's happening.

It should be more like "Insulation is less effective" or the such. Because that's what those downsides do. They subtract from the summer/winter insulation of the player.

However, insulation can not go below zero, so it only ends up affecting you when you're wearing insulative clothing.

@Hornete
I’ve been retesting it and I see what you mean..  Huh, weird!  So a negative value just means you’ll need more protection to have the same affect as someone else, got it!

I guess this is solved then, but the wiki could be more clear.
