Gleba Carbon Plus
This mod idea came about after a recent modded playthrough involving the Ballistic Missile mod, which requires Light Oil to run. While Space Age offers the ability to directly produce coal through the coal synthesis recipe, it is very inefficient for usage in Coal Liquefaction on Gleba, requiring you to either import the materials or to set up a much larger operation to sustain the factory.
Keeping in the spirit of Agriculture and "growing products", I decided to come up with a way to change this behavior. This mod adjusts the behavior of the base game's tree seeding recipe, and when completing a new technology added by the mod, grants the ability to plant trees on Gleba which will allow you to automate wood. A second technology then unlocks a recipe that allows you to blend Wood and Spoilage in a Biochamber to get Coal directly.
On the side, I have also added an infinite productivity research to Gleba for the two fruit processing recipes and the Bioflux recipe. There is a setting to disable it if you don't want it, and also a setting to control the cost scaling if you feel the default is either "too expensive", or "too cheap". I have also included the ability to fully customize the Biocoal recipe directly so you can make it as expensive (or inexpensive) as you feel fits the "fair" experience of your game through mod settings.
Feel free to toss any issues you run into on my Git repo and I'll take a look. If you would like to localize the mod to another language and can translate what is there, feel free to throw a PR on the repo as well.
