I have have had exactly the same problem as shown in the big photo -instead of looking as shown in the original download advertising photo.
Like you i have had the INIBUILD rendition of the Queenstown Airport since it first was available and I appreciated the product, as in my travels down there in the past, that was what I was used to seeing, during my time in the area - Alpine Climbing and Skiing.
I did had to get MSFS2020 re installed during the week just gone - and so the problem has arose since then. The thing is that I have re installed every other Airport in NZ - which have been available from other providers - and all of which re downloaded perfectly in their original form.
And so the question is - why was INIBUILD 's Queenstown Airport the only one effected by the latest NZ world update, or by the re installing of of MSFS2020??
