can I have a save file please and a copy of your mod-settings.dat

you can use wetransfter.com, or something else.

I tested this change without getting any issue, so I wonder if its a combination of other mods.

just a few mods :)

yeah just one or two :)

OK, it looking like Angels "Components overhaul" is messing up some of my logic. Needs some more work after bed.

Please try updating https://mods.factorio.com/mod/DeadlockStackingForAngels .. the "Component mode" setting for angles changed the recipe for gears and confused this mod.

Works! Thank you so much! Also I would like to request a stacking mod for the madclown's angels mods if you got the time to spare.
