Hallo Matthias,
not reproduceable sorry. When the sim crashed (whatever for reason) - you get no error report - that´s a sim limitation, sorry. Can only be added by ASOBO/MS. There are a lot of such requests in the official MS Flightsimulator forum.
Here a planed flight from EDDP to EDDB - no CTD.
… and here to EDAH:
Using AIRAC 2101 revision 2.
I would try this one:
FAQ - Scenery-File re-organisation / initialization
But it looks, it´s a local issue on your system … possible someone else can test a route between EDDP-EDHA or EDDP-EDDB - I can´t reproduce your report sorry.
Cheers,
Richard
