It just seems to ignore some of the ground "waypoints" which it didn't in the past.
There was a change to the taxi routing code a while ago to reduce the number of points passed back to TGS.
The taxiway definitions in MSFS 2020 are so granular that we were seeing very long lists of waypoints where many are actually on the same taxiway.
We're only really interested in significant turns and moves from one taxiway to another, so long runs of 'do nothing' waypoints are now removed.
That isn't what's happening here, the waypoints I'm showing on the diagram are the only ones in the airport data (FS2004 data is quite simple).
However, I want to check the details that were passed back to TGS as it is possible that something needs tweaking.

I've looked at the code and have been able to make a simple change that gives TGS better information to handle situations like this one.
The updated code has been passed to Dave for inclusion in a future beta release, at present I don't know when that will be available.
Thanks for bringing this to my attention,
Martin
