I installed this as part of a new test modpack we are making. After the recent update the rate of body temperature change was much faster. While trying to learn to change the setting I set enable body temperature to false. It had no effect. Players were still freezing to death.

Forgive me if I missed something obvious, I am fairly new to this.

I'm not sure myself, 1.11.2's temperature system is certaintly not working as intended, I ran it and with biomes o plenty I was constantly dying of hyperthermia in the middle of an oak forest, I have to constantly dive int othe nearest water source to avoid dying. There needs to be a toggle to enable/disable the entire temperature system as a whole in the Mod Options menu as I love the thirst and health mechanic but the temperature is simply overkill right now and is compeltely unmanageable. Realistically unless you're living in Australia's forests or a desert biome, you shouldn't be constantly fighting hyperthermia, it's unreasonable.

Okay @mohler7154 I managed to disable it in the CFG files. I did two things. I set the following line to 'false' in the file "/config/toughasnails/temperature.cfg":
B:"Enable Body Temperature"=false
I then copied that line and deposited it into the "/config/toughasnails/gameplay.cfg" config file, also set to false. I believe this just lets you toggle it from the Forge Mod Options menu.
However this worked to disable it for me. Good luck with you, I know mods are finicky.

The option to disable body temperature was moved to a different config file (temperature.cfg), as Rexhunter99 noted.
