I believe there are two confusing issues here. The ONLY item that is missing, are a few block houses outside the airport, which are supposed to be in the same area of some trees. None of the airport buildings was ever missing.
To the one that said the Live Update "fixed" this, he was probably referring to something else, and in his case it was fixed because he had something outdated.
There hasn't been any fix for missing houses outside the airport because, as I've said, we don't understand the cause so, there's no such thing as a "disappearing fix", because there wasn't any fix for the missing houses in the first place. We'll post it here as soon as we find a solution.
