I think I’ve discovered a related issue. Recently KXNA renamed their runways to RWY 16L and RWY 16R (34L/34R) and this hasn’t been updated in sim to reflect the updated AIRAC data. This can manifest itself as not showing approaches and runways properly in an FMS.
Unfortunately I doubt we’ll see a fix until the World Hub, and even then it’ll be up to whether someone on PC makes the time to fix it and there’s enough dev capacity to approve a fix sometime this year (I’d say maybe a 50/50 chance).
