Hi,

The Factorio 2.1 port is nearly complete!

We've been preparing ATRM for Factorio 2.1 for quite some time, but Wube's last-minute API changes caused some unexpected complications and required additional adjustments.

ATRM 3.0.2 DEV is now running successfully on Factorio 2.1.23, including the first successful K2 + SE + SEI compatibility test. The major API changes, technology progression issues and Foundry conflicts have been addressed.

The remaining work is mainly final compatibility testing across Vanilla, Space Age, K2, SE and K2SE, along with savegame migration checks.

My personal goal is to release ATRM 3.0.2 tomorrow, Saturday, October 24, provided the remaining tests pass.

This first 2.1 release will focus on restoring existing functionality and compatibility. Larger gameplay changes and new features will follow in later 3.x updates.

Thanks for your patience!
Greetings

thank you

Hi,

ATRM 3.0.2 – Factorio 2.1 update is ready! 🎉

The port to Factorio 2.1.23 is complete, and the final release package has passed our initial compatibility tests.

We've successfully tested six configurations:
- Vanilla
- Vanilla + Space Age
- Krastorio 2
- Space Exploration
- K2 + SE
- K2 + SE + MoSII-SEI

The largest test configuration contains 3,774 recipes, 900 technologies and 104 resources, with all major validation contracts passing and no technology dependency cycles.

I'd really appreciate your feedback!

If you encounter any issues, especially with existing savegame migrations, missing recipes, technology progression, machines or mod compatibility, please report them here.

Ideally, include your factorio-current.log, your active mod list and versions, and a short description of what went wrong. For migration issues, please also mention which ATRM version you upgraded from.

Even small inconsistencies or unexpected behavior in your particular mod configuration are valuable. They help identify hidden bugs that our own test configurations may have missed.

Thanks for your patience and support!
