Rhino Block Tools plugin. SelSameBlocks is "unknown command."

I was certain this command worked previously. MakeUnique, and ResetBlockScale work, but SelSameBlocks is unknown command. Thoughts

BlockTools 1.4

I’m not familiar with this “BlockTools 1.4” plug-in.

Perhaps @ejnaren has some insight.

Wim is right. It is created by ejnaren. I’ve been using it ever since I discovered it gave Rhino the “make [block] unique” feature that I use extensively in Sketchup.
