So while I was in fact using the LN-NGM livery from PMDG, all AI traffic/multiplayer was off as I typically don’t like to fly with it on due to performance.
Someone else in the thread noted having the issue on final for 01L (forget to mention RWY in the OP).
I haven’t had time to get back to it, but after reading through the thread the Nool Aero VDGS fix seems to be working so I’m going to start with that one and see what happens.
Will report back later with findings. Thanks to all who have contributed ITT.
