BUG FLOWONSRF on Blocks

Rhino Rhino for Windows

Hi Guys,

The FlowonSrf on this specific file doesn’t deforms blocks nor apply them along the surface.
The Blocks are grouped togheter with the other geometries.
To me looks like a bug: I’m expecting, at least, that each block would be wrapped rigid along the surface and not treated as single group.

I can’t share the file in here, there’s an email for a more confidentail submission?

As you can see in the image the blocks were applied as “Rigid Group” but the option is RIGID=NO
The bug seems to appear when the blocks are grouped.

Thanks
