No other planes to be seen in this, or any other, landing challenge that I’ve seen.
Each landing challenge only requires one plane as a minimum dependency* ie the plane you are flying.
Thought: is there any part of an A320 that could be used in a CJ4? (at least in sim terms)
Just to check, I also deleted the folder and re-acquired it through the content manager (in World Update 9 aka Italy) and the error/problem is still there.
Clearly a bug/error/fault, call it what you will.
The only easy way to check the rest are not bugged in a similar way would be to compare the manifest.json files to each landing challenge.
Some extra info that I’ve found:
There appear to be two ‘types’ of landing challenges : Asobo and Microsoft.
*looking at the manifest.json files, the 27 of the 34 Asobo ones require an Asobo plane - rest are missing that tag; all 24 of the 24 Microsoft ones (maybe added on/after June '22?) require an Asobo plane of some sort.
The 7 missing an aircraft dependency are:
Asobo-landingchallenge-biis-isafjordur *
Asobo-landingchallenge-efva-vaasa *
Asobo-landingchallenge-eg78-outskerries
Asobo-landingchallenge-eghi-southampton
Asobo-landingchallenge-ekrn-bornholm *
Asobo-landingchallenge-ensb-svalbard *
Asobo-landingchallenge-essa-arlanda *
(Oddly, 5 of those (starred) were the only Asobo ones not updated recently and all have Jun/Sep '22 dates on my PC - not sure what to make of that.)
As a retired programmer, and ‘habitual completist’, I would be uncofortable with the lack of a dependency in those files as well.
FYI The other 4 MS challenges, that require an A320, do not appear in the choice of challenges that I am presented with when in game - that makes some sense but it makes me think that there’s another file somewhere…
