Hi Phantom-Phreak,
Thank you for reporting this issue and taking the time to point it out!
You were absolutely right. After a closer investigation, I found an issue in ATRM's early steel production progression when using Space Age.
The problem was caused by an outdated compatibility adjustment that assigned steel production to the wrong crafting category, preventing it from being produced in the intended alloy furnace.
I've now corrected this, along with a few related issues affecting early graphite production and the alloy furnace requirements.
The fixes are included in ATRM 3.0.4.
All six of our supported test configurations have successfully passed the startup and prototype analysis tests.
Thanks again for bringing this to my attention! Reports like yours are genuinely helpful, especially when they uncover progression issues that aren't immediately obvious during testing.
I really appreciate your help!
