This fix solves the CTD at world map and works under current SU14, so there´s definitelly a solution for the issue and you can now spawn normally at Tegel. Gaya should be able to reactivate airport as well, by overwriting the original ICAO code that is included in existing game´s data base, so that EDDT becomes active again.
