A bug has turned up in LOM 2. If you try to load FS9 libraries into the FSX version of LOM then the information about Footprint and textures does not make it into the database. The problem has been found in the switch which sends FS9 stuff to one de-compiler and FSX stuff to another. This should not affect the ability of LOM to place objects but the scale will be wrong if you try to use them in Scenery Maker.
There is afix and a new version should be out within a couple of days. In the meantime FSX objects (all 3,515 of them!) are imported correctly.
