Frankly, I’ve looked far and wide and haven’t found the ditch. On my version (MS Store) everything is fine apart from that huge building between the apron and the taxiway.
However, I would like to add that from the attached photos @Aerojive there is something wrong, I doubt it is at DNAA. The photo shows that Nnamdi Azkiwe Intl is slightly off to the right at a distance of 4km (ARP) while as you can see from the attached photo from runway 04 the ARP is in the middle of the runway at a distance of 1.79Km.
