Okay so I just found my old heat packs I got las year and it kinda hit me that there aren't any in the game. Wouldn't these things be useful in a place like this? I'm not sure if all packs are multi-use or if serious longtime heaters would "burn out", but mine can be "reset" by just "cooking" them in boiling water so I guess they could make a useful "just have to reach the front door/must harvest this deer" item in times of need. - Condition would be based on number of uses, each use lowers it b
