However, I did not ask you for this answer
Since this is our own support forum, replies will come whenever we believe they are necessary.
because your answer is exactly a beautiful example of the way you lead this forum
Exactly: with the utmost attention to giving correct answers and trying not to confuse people.
Since discussing two things that are ENTIRELY unrelated, which is partial vs entirely missing buildings, as if they were in some way related, WILL confuse people and will only result in wasting their time applying solutions that are correct for only one type of the problem, to an entirely unrelated one, it's important I will always repeat this, because not everybody (nobody, in fact) reads all threads entirely.
I'm a member of many forums, and in almost all forums: forum members try to help other forum members, and the forum leader is (of course) invited to contribute, no doubt. But, please don't make this a two-way discussion again
This is not a public discussion forum, it's our own support forum, which means users should always ask to the source for support, if they have to rely on other users for help because we can't fix their problem, it means we are failing doing our job as support, and we don't have the slightest intention of even start giving the impression we don't support everyone as best as possible.
So again to the forum members: let's try to find the solution together.
There's nothing to be found, because there's such thing as "the" problem. There are lots of different things that can happen, which requires to be dealt separately and with different solutions.
If anyone still doesn't see buildings after installing the latest KLAX 1.1 and after being sure no older installers were launched after it (in this case reinstalling the latest KLAX 1.1 or the latest Addon Manager will fix it), report here, and will see his own specific case and will look for his own specific solution.
If anyone still sees partial buildings, it's probably better to open a separate thread about this, because it's nothing related to KLAX, not directly at least, meaning KLAX is made in a way that is triggering some kind of video driver problem that you already had, or a memory leakage you already had.
