Just to bump this up again, I have had quite a few Fusion crashes (not system crashes) in the last couple of days, and I now notice when I go to apply materials that there are only a very few available- either showing as in the document or as available in the Autodesk Materials. The weird thing is that the appearance materials still display in the drawing- I've got an orange plastic, for instance, that no longer appears in the list, but displays as before the crash. I'm not getting the missing materials dialog, and there are still libraries there, but I don't have anywhere near what I downloaded, or even what is in the current design. I've downloaded quite a few materials, but I think all I see now is the default batch.
Materials definitely seem unstable, and the interface is not very good- for instance, when using the Material command, it would be nice to see what the current material is- probably jump to that in the interface. That would be nice when you want to apply the same material to several parts, but don't recall exactly what it was.
