No, I don´t use the Windows Inside version - I´m always on the stable version. Possible that is the reason why it works here and not on other system but I don´t know.
What I have done now is:
I have compared the previous version with the current version and again, ASOBO/MS has removed a lot of airports - also existing one (ie. 08AR, OEPA, NTKK, WAFO, …), plus they added a few (ie. NZAG, NZOB, )…
In the past, this was exactly the issue …
I´m not sure, why they add, change or remove existing airports with nearly every update but they do it on every update now (in the past, I thought, it´s only with the WUs). For us, it means we should rebuild the AIRAC files again to be in sync with the MSFS.
I´m not sure, if this will help because I can´t reproduce this issue as you see - also not with the new TEST.PLN files from @Joburgal
… loaded correctly on my system, sorry.
… exactly that is wired … why does this work with the FLT format but not with the PLN format? Both use the same data … I´m still be sure, that there is somewhere a bug in the MSFS but I can´t say where and why, also why this doesn´t happen on all systems. Most of our users have no issue … also I.
So, main question again:
Do you have installed ALL!! World Updates (possible it´s enough, at least the latest WU13 “Oceania & Antarctica” update) and are all “Up to date”?
Cheers,
Richard
PS: silly question - I miss WU 9 …
