Ghost Airplanes (Missing Textures at Chinese Airports)

This is something I keep seeing at Chinese airports.

A while back after the installation of two sceneries, JetwaysAndTerminals ZSPD (Shanghai Pudong) and FRF's Beijing, after spending a decent amount of time there, texture of other aircraft begin to disappear. At first I thought I must've done something wrong with the newly-installed AI aircraft, but soon enough, all aircraft, and finally mine would become "ghosts" (and the scenery as well I think (not fully confirmed)).

Not only that, but I believe this may have contributed to many of my addons losing several of their structures (i.e., cfg's, texture folders, other folders, etc.), so I'm always too afraid of being at an airport with these effects for too long.

Actually, the loss of these files may have been due to another problem which, may have been separate from this one (out of memory error I believe).

The last time I observed this error was at Chengdu's airport. I landed and all AI was gray. My aircraft also went gray shortly after.

One other note; when I installed the ZSPD scenery from JaT, I had to add a landclass for ZSPD, as well as an AP###### file (I actually went back to the original one since I feared this file would've tampered with other Chinese addon sceneries).
