The problem is mainly due to internal changes for the
FlightGear roadmap, for standardising the code, and improve stability (in technical terms: among many other changes, the
parking positions were dropped from the nav data cache to improve support for dynamic airports). This has broken things on the AI side, but I assume that the developer behind the AI code has been quite busy with real life to look into this. I tried to look into fixing this, but it was a bit much for me. If I find more time, I might look into it again. Anyway, a detailed message to the
flightgear-devel mailing list with a good, isolated example at a not too complicated airport in the TerraScenery database (TerraSync) to show off this problem, and also where to look, how long to wait, etc. would significantly help in finding a solution.

P. S. I might have misread your earlier message about your repository being forked, and thought you were giving up on LFLL. Keep up the great work, the TGV station is looking awesome!
