buggy normal flipping of surfaces

I think i found a bug - the behaviour that I'm encountering doesn't make alot of sense to me but maybe someone could enlighten me. I have a list of surfaces that should be oriented in the same direction but aren't. I tried using the flip normals component and it seemed to work when I checked via baking the surfaces but the normals - which is really what I'm after - haven't changed from their pre-flipped state. I am evaluating the normals via an Evaluate Surface at uv component... Does that make sense to anyone? Shouldn't the normals be flipped?

Yes, there's a known bug in the latest version were GH doesen't check if the surface was flipped. You can still "flip" the surface by reversing the U or V directions using the same command.

"using the same command"? which one is that? I had to do some acrobatics to get the surfaces oriented properly...
