I just got this awesome Roguelike (Windows Installation) last weekend when I heard about it because it was mentioned in an article that Rock Paper Shotgun linked to. And, I, too am running into the perpetually “Cold” bug with no previously existing characters or templates.
But it might just be a cosmetic “Cold” warning appearing on the bottom, because it does not seem to affect my morale or anything, it just says “Cold” down there in the status bar the majority of the time.
Aside from that, the game’s been working fairly well. I did run into a crash when I tried to enter my first cave, though. That and some other crash I wasn’t sure what entirely caused it, but it might be related to the “none” inventory slot on starting NPCs (there’s a C:\cygwin\home\Kyratzes\Cataclysm-DDA\game.cpp[7987]: Static NPC with no fine location data (8:-1). message that popped up some time before it happened during the same game).
