Hi,
I am not sure if this happened due to the Nordic update, but the runway exit taxi-signs, circled in the attached screenshot, are underground. I checked that they are actually there with a terra-forming test. I think they just need to be placed separately due to the sloped/elevated terrain made for the airport between the runway and taxiway/apron. Sometimes the far end signs show up, depending on runway selected for loading the sim.
Thanks,
Steve
