In the oil preview build the Exosuit Forge says it requires 480 W of power and a gas output pipe, but the type and volume of gas produced is unlisted. I don't know if this is a bug or an oversight, but to my recollection every other building that produces a gas or liquid lists the type and volume.
Steps to Reproduce
Loaded a pre-existing save in the oil preview build
