My new 1.6 scene initially rendered fine.
Imported some earlier 1.5 objects that had earlier been saved as 1.6.
Reopen scene and most of the orginal materials (the materials assigned prior to the import of new models) have vanished.

The materials that dissappear are still in the material list BUT the material
icon is gone in the material list AND the object list.

This seems to happen when new imported objects contain a material that is already present in the scene.

The materials then vanish when the mxs is reopened after saving.
Extremely annoying having to reassign 400 mats.
