Version: Atomic+Space+2.0.1

Crafted/placed/lit a campfire and am standing in the block space right next to it and am still losing heat. Also the torch next to it does nothing as well which seems like it should do /something/.

I think this is just a mod issue

Ok, as far as the campfire, it does indeed work. It stops you from getting hpothermia. In Forever Stranded it was set to 15, in this pack 5.. so yea, not very effective.

There are however a bunch of other blocks like the torch that could use some love in block_temperature.json: minecraft:torch, silentgems:stonetorch, primal_tech:fibre_torch_lit, primal_tech:charcoal_hopper, torchmaster:mega_torch, actuallyadditions_block_tiny_torch and darkutils:sneaky_torch

Ok, thank you for your suggestions I will add them in the next update
