Hi Sylvain. Yes, I have exactly the configuration you described:
runway taxiway segment between the taxiway entries to make the AI to taxi
towards the start points, to no avail. Effectively the start points are being
ignored. You can use the same package I provided earlier
https://devsupport.flightsimulator.com/t/5344 about the bug with the
performance hit when moving projected meshes and taxiway points (which is
still there on 1.31.22 btw). That package contains my current taxi/runway
layout as well. Thanks! Denis
