I've noticed a couple of third party aircraft I've downloaded (like the Stanford-Tuck Hurricane) has a tendency to sink into the ground and half bury itself like its stuck in quicksand when its standing next to whichever aircraft is selected in the options screen airfield view. Its not a major problem, as once you select the actual aircraft it pulls itself out and stands on the ground in the correct manner, but purely for the aesthetic value, has anybody else notice this and is there any way to fix it ?
