V6 Bug?: Locking layers cause objects in block instances disappear

Rhino 6.6 RC : just noticed that when the layer of block object is locked, the object is not displayed (as if the layer was off). Seems like a bug. Works fine in Rhino 5.

See attached sample file - try locking the Layer02 or Layer03 - the objects will disappear.

Hi Jarek - yep - got that, thanks, it is on the heap.



Hey @pascal

This is now happening to me. I’m on the most recent 6.6 SR7

Didn’t happen before for me.
