The kitchen re-model hadn't involved the moving of outlets or the rerouting of cables in any way.
Continue to think "parallel paths," and go back to the screw/nail idea.
Do you have a neutral to ground fault were the flow to the fault only breaks the 100 milliamp barrier when the neutral is heavily loaded and the voltage drop creates enough of a voltage difference to drive the leakage current beyond the trip point?
