Failed to load mods: Error in assignID: recipe with name 'bre-roboport-mk2' does not exist.

Source: BRE-construction-robotics-2 (technology).

I double-checked all BRE technologies and recipes and couldn’t find any reference to bre-roboport-mk2.
The error is most likely caused by another mod patching a BRE technology and still using the old recipe name.
Please test with only BRE enabled to confirm.

oh ok then it would be my own patching that broke. sorry

Well the crash did disappear when resetting your mod settings

No worries 👍
Thanks for the update — that makes sense.

Just to clarify on my side: internally I renamed all roboport-related prototypes to be consistent.

The names were changed from
bre-roboport-mk1/2/3 → BRE-roboport-mk1/2/3,
and this was applied consistently across items, entities, recipes, and technologies.

There should no longer be any prototypes using the lowercase bre- prefix.

The migration is applied automatically when loading existing saves, so old roboport names are updated when loading a save created with an earlier version.
Resetting mod settings can help in cases where older configurations reference outdated names.

If something still references the old names, it’s most likely coming from custom patching or another mod.

ok
