Well, I had that decryption thing happen and came here- then I installed the KIAH update
So that problem was fixed.
now I have floating light beams over terminals and aiming out of runways and other airport areas.
Do you use FSX SP2 ? If yes, it's likely you have the same problem found in KMEM (that doesn't happen on FSX+Xpack, FSX:SE and P3D) that, because of an FSX-SP2 specific bug, some objects that are entirely and totally legal and SDK compliant, are displayed rotated.
We found a workaround at KMEM, but nobody ever reported a problem at KIAH before, but we haven't changed those objects in the update, but we'll check this and will add the same fix used for KMEM.
I also have AI jets sinking in the ground at terminals.
This is nothing we can do about, and the scenery always was like that. In order to prevent ground flickering that would otherwise caused by using the native FSX ground polygons instead of the slow FS2002 polygons other sceneries use, we must raise the ground a bit depending on your altitude. This will result in AI sinking their wheels into the ground, but it's either this, or it's heavy flickering.
