BUG: Purge command purges used materials

Hi all,

I have a bug in Rhino 7 where if I use the purge command, it will remove used materials as well as unused materials. Did I do something wrong? or is this the intended use, how do I purge ONLY unused materials?

hi @Nick_Cassab that should not happen, Can you share a sample file that demonstrates this issue? Pls also provide your _SystemInfo, thanks
