RGH Strange Coolrunner issue

Hi All.
I've flashed my NAND several times with different builds. The latest build doesn't cause the console to glitch, which is odd as the last one worked fine.
I was testing my soldering when I came across some stange behaviour.
When I touch the probe on CPU_RST the green light will flicker or come on completely. The continuity checks out fine for the wire though. Happens even if the probe's not connected at the other end.
I've not had it load the dash yet but I wonder if it's something worth investigating, maybe a solution to the issues with the Zephyr.
Does anyone have any ideas what this could be doing? Adding resistance? Altering the timings?

The CPU_PLL_BYPASS is really senitive, I'm not sure what you are doing in a good idea and yes you are adding resistance, altering timing and who knows what else

Could do with someone more technical than myself taking a look. There may be a way to improve booting on Zephyrs using a resistor, diode, cap etc on this point but I've no idea where to start other than just sticking one on and seeing what happens
