Purge removing Rhino materials

On SR18 09/10 I just noticed that the Purge command is removing basic Rhino materials that are assigned at the object level, materials assigned to at least one layer remain.

Hi Jim - yikes! that is not happening here so far - do you have a file that shows this?

Wait… I see the reverse - a layer material on a layer that has no layer-assigned objects is purged.
Hm. I cannot repeat this.


Yes I have a file, I’ll send it privately.

Was this problem ever solved? I’ve been having the same issue and this was posted almost a year ago.
