I wanted to say I have been having a lot of fun with voidblock and I really appreciate all the effort you have put into these mods.
I find that the Thruster Propulsion recipe (use 5 void fuel and make %50 of 300 Thruster fuel and %50 of 300 Thruster oxidizer) seems a little odd. I understand it aligns with the rest of mod with making percentages of items. However, excess items can typically turned into void flux but not Thruster fuel/oxidizer. It can only be consumed in equal amounts in a Thruster, so as time passes and with how percentage based creation eventually leads to deviation, you will always have more of one than the other. I would understand if it was part of some sort of challenge with turning excess fluid into something else. But since there is no such option, the only thing I can do is just manually flush excess fluids from the storage tanks every once in a while.
Wouldn't it be better if the recipe was just 5 void fuel into 150 Thruster fuel and 150 Thruster oxidizer?
