Rhino Keeps Releasing SubD from Cage-Bug?

Hi, I’m trying to edit two SubD objects and one polysurface at the same time with a cage. After the first couple of changes to the cage points, one of the two SubDs (always the same one) gets released from the cage, and further edits to the cage only affect the remaining SubD and the polysurface.

I can re-add the subD to the cage, and then a change to the cage control points will show a preview of that subD changing as would be expected, BUT if I release the control points and make it do that change, the change is only applied to the other subD and to the polysurface.

SelBadObjects does not turn up anything.

Thank you!

Thanks, I’ll test this - if you can please post the three objects or send to tech@mcneel.com, with a link back here, to this topic, in your comments.

Thanks Pascal, you know what, I think I just figured it out. I had to “release all objects from cage”, delete all cages, then I could successfully make a new cage that affected all normally.
