with
recipes.removeShaped(thermalexpansion:satchel:2, [
[null, gregtech:meta_item_1:9126, null],
[gregtech:meta_item_1:10112, thermalexpansion:satchel:1, gregtech:meta_item_1:10112],

fixes the issue.

Expected Behavior:
to be able to color/lock Reinforced Satchels

Steps To Reproduce:
Look at uses for Reinforced Satchels and see there is only one recipe (upgrading)

Crash Log:
n/a

Screenshots:

The code change you suggest works incidentally because you used the wrong metaitem ID for the electrum nuggets (they're 9112, not 9126) so it fails to find a matching recipe and thus nothing is removed.

Looking at a comment in the script, it seems the reason this recipe was originally removed and re-added was because at some point in Omnifactory's development history, Tinker's tables were in the pack and they apparently wouldn't JEI fill-in the item properly with the original recipe. This is of course not a concern as that mod is not in the pack. I can just remove that whole block from the script.
