Items do not transfer heat to solids they are touching, only gasses and liquids. This results in a strange behavior where a liquid in a vacuum that turns into a solid item will no longer conduct to the surface it was previously resting on.
Steps to Reproduce
Place a few kg of liquid in a vacuum touching a heat sink. Once liquid cools into an item, observe lack of heat transfer.
