Probably this has something to do with the directX version on those machines. I guess DirectX is frequently doing garbage collections and this may differ on various DX versions. So if you free an entity, physicly it's still there and the handle may even still function, at least until the next garbage colletion will "officially" free or overwrite this memory area.
That's why you should set a handle to zero after freeing its entity, eg:
FreeEntity mesh
mesh=0
This way you will always be able to see if an entity exists.
