I did re-run Live Update and noticed KORD v2 files downloaded so perhaps that was the issue.
No, it wasn't. We just added the missing red runway enter markers on hold short zones.
The floating objects only render on final approach after a long flight.
Them I'm afraid is the very well known bug of P3D 4.5, which in this case can only seen after a long flight. We *MIGHT* be able to fix it, because it affects only objects in .BGL file format but, for this scenery, we wanted to be as native as possible, and don't use too many Simobjects, which cause pauses when loaded or destroyed.
In our previous sceneries, we used Simobjects a lot, to bypass some limitations of the FSX SDK, but since it's not required anymore in this scenery, which is the first one that is made specifically for P3D4, there wasn't too much need to use them, since the P3D4 SDK give us lots of flexibility without having to use Simobjects, so we choose the smoother .BGL format for most of them.
This means, unfortunately, some of our objects will be affected by this 4.5 bug, which doesn't happen with 4.4. We DID use the Simobject format for SOME objects that we *know* they "ghosted" in the air, but apparently some of them cause a problem only after a long flight, but we would rather not going back to use Simobjects entirely, because it will affect the smoothness of the scenery, and create long pauses on loading it.
LM is fully aware of this problem, and I'm sure they'll release a fix for it soon enough.
