Doh! My bad, somehow I had copied one of the fanout vias onto C4 by mistake, just checked the original and it's not there. Sorry for the confusion.

do you have a different gerber viewer you can try?

Don't know which of the reference layouts you are looking at nor which tool you're using to look at them. I just looked at all three I think are current, normal, DC/DC and NFC and, on my gerber viewer there is no such connection, the P0.11 trace meanders correctly away on layer 1 and emerges untouched. My viewer doesn't show a via where you have 'GND' marked on your diagram.

If there was it would be an error since it's not connected on the schematic.

I got the reference layouts from the infocenter off infocenter.nordicsemi.com/.../nRF52832-CIAA_Ref_Layout_v1.0.zip that link.

You can definitely do this on a 4-layer board, it's not even that tight.

Or rather, C4 is the actual GND pad, C3 is marked as NC in the schematic but is, in this case connected to GND via the P0.11 trace
