The pads shown with the yellow unrouted line are both GND. They are both surrounded by a ground plane, which is also connected to GND. Hint: it isn’t a bug and it is something many people might ignore by mistake. Can’t figure it out? Or you want to see if you got it? Use a ROT-13 converter for the answer: Gurer vf ab culfvpny pbaarpgvba orgjrra gur tebhaq cynar gung P9 naq 3I3_CJE ner fvggvat ba.
