Liquids do not boil in vacuum

Currently, liquids do not boil when exposed to a vacuum. In real life, as pressure decreases, the boiling point of a liquid decreases. For example, when exposed to a near vacuum, water instantaneously boils into a gas.

This probably arises because the game models solid/liquid/gas matter phase change by determining solely the temperature of the object, and assumes the atmospheric pressure is fixed at 1atm (e.g., the pressure at sea-level). However, the phase change is actually a function of both temperature and pressure.

I debated whether to add this as a suggestion or a bug. Because the game models temperature, matter phase change, and pressure, I think the lack of interrelated behavior is probably an oversight or bug.

Hmm, I'll mention it to the designers, but I'm not sure what their intended functionality is in this situation.
