Thanks for the feedback!
The updated recipe-change detection can indeed trigger MK1 generation when another mod (or your own patches) already modifies the robot recipes. That’s why you’re seeing duplicated entries now.
To prevent this, you can set the MK1 mode to “Disable” — this stops BRE from creating any MK1 recipes and keeps your own patches intact.
If you want full control from your side, I can also add a small compatibility interface — for example a flag or trigger that your mod can set to tell BRE to skip the MK1 generation entirely.
If that would help, just let me know and I can add it!
