Hmm.. I was able to recreate the issue with that setup, though I wasn't able to figure out the cause. Running with Bob's Modules and Space Age works fine, running with Reverse Factory and Space Age is also fine, but running with all 3 causes the issue. But as far as I could tell, neither of our mods actually touches the copper cable recipe in any way.
However, simply considering the fact that I was able to recreate a very similar issue with Bob's Electronics by itself, I want to say it's more likely that this is a Bob's mods issue. Unfortunately, it's impossible to tell without a much deeper investigation (outright disabling/removing portions of code from each mod, like a binary search pattern).
I would suggest bringing this up to them first, in case they have any idea what the cause could be, before I go that deep into the weeds, especially for a relatively minor issue, that only appears in a very specific and unlikely configuration of mods (I can't imagine Bobs + Space Age is that well-tested or balanced?)
