As you can see in the screenshots below...

...there is a problem. I also noticed that when I spawned on the active runway, I was to the left of the center line--AI was too. And, the AI planes are parked pretty much with their noses sticking into the terminal, and when I spawned at a gate, I was in the middle of a baggage cart, and there wasn't a jetway there at all.
I hope this is a simple fix, as it looks beautiful in any case.
