The intersection data appears to be wrong at EDDF.
I am importing the Navigraph database into TOPCAT and the resulting Database.tdb file reads as follows:
#Worldwide Navigation Database

Note the following intersections:
None of these appears to exist in real life, or on Navigraph’s own charts, with the exception of 18/S.
Can this data be updated? TOPCAT overwrites any manual changes I make when the next Navigraph update is applied.
This would be the correct list, to the best of my knowledge:
Intersections at airports such as EDDM appear fine by comparison.
