Hi.
First of all, I didn't find any dedicated place for discussing weird interactions while running the entire suite, so I'll post it here.
So, currently found a couple weird interactions playing full suite + QoL.
1:
Water electrolysis => Hydrogen => Oil burner => Steam power is somehow energy positive (no modules).
This breaks thermodynamics if I'm understanding correctly.
2:
10 Coal + 20 Coarse Fraction => 60 Tar recipe is useless.
You unlock this recipe at Basic electronics (green sci), all the while having 10 Coal => 0.3 Iron Oxide + 6 Coke + 40 Coal gas + 50 Tar from the very beginning of the game.
At Coal processing 1 (red Sci) you unlock syngas from coal gas, turning the overall chain into:
10 Coal => 0.3 Iron Oxide + 6 Coke + 0.8 ash + 80 syngas + 74 tar.
So at green sci you unlock recipe to add coarse fraction to get.. less tar.
3:
Wood to coal recipe is useless.
At Coal Processing 2 (green sci) you unlock 2 Wood => 1 Coal recipe.
But already at the very begining you have the 10 Wood => 0.3 Iron Oxide + 10 Coal + 10 Coal gas + 30 Tar
Same situation as above - more advanced recipe is less efficient.
4:(?)
This isn't tested (haven't reachet this stage of the game) but from FNEI multiple high-end animal breeding recipes are cage positive.
IE, from 1 cage + food etc. you can get 2 caged animals => 2 cages and 2 fully rendered corpses.
Vrauk example:
3 Water barrel + 1 cage + 1 bedding + 5 Sap + 1 Antivirals r + 1 Quality Vrauk food + 5 Fawogae MK1 + 5 Moss => 1-2 Caged Vrauk.
Unlocked at Antiviral Drugs.
