I waited to test in for major patch today before posting this since I knew it was coming but the problem still persists. My character is always warm, this started after the patch that fixed always wet for others.(I was never always wet) I am not wearing the cursed armor set at all, but I have worn it in the past. Since this bug started I have tried remaking my character multiple times in the mirror, killed and resurrected them, put back on the entire set of cursed gear and removing it in any order, tried killing the character while wearing the full set and removing it before resurrecting them, killing them while frozen, anything you could probably think of and all of the above again after the patch.
