How was this working?

Installed an hwfly core (v2? The ribbon had M6-1 I think) about two weeks ago with no microscope. Fun fact, if you accidentally knock off the two tiny capacitors on the left side of the CPU it puts the switch into permanent airplane mode. No wifi or bluetooth. I had a hot air station, but no way was I going to try to reflow those tiny 201 capacitors without being able to see them so microscope ordered and capacitors fixed, yay! Fast forward another week and I updated from 13.x.x to 14.1.0 via the OWF. Now Hekate no longer worked, the chip would flash purple then change to green, but the OFW was already booting. Apparently this is a separate issue but it lead me to teardown and examination of my connections with the microscope. To my surprise, I had totally missed on SP1. No connection to either side of the capacitor. This leads to my question, how was the chip working with no connection to SP1? I had used it for almost two weeks with no issues and likely would have used it longer if not for the update snafu.

Electronics work in mysterious ways.
SP1 is probably just connected to the power rail.
Likely 1 of the connections is just a ground connection that is connected somewhere else.
Maybe the other connection was just touching the capacitor.
Or something more scary was going on like power bleeding from somewhere else.
