Stereo tracks sending to Quad Fx returns

Hi All, I wonder what anyone’s thoughts are on Fx returns that are going to a quad output , but VSTi sending to them are mostly if not all Stereo ?

There was a bug C12 which I reported and got fixed in C13 , where after a export the FX output would change its pan position that’s now been fixed.

So how are used to work (before Cubase) was stereo in quad out in Logic and PT. If I had any actual quad instruments or tracks , I would then create a quad in specific Fx for them.

Just not sure of the implications of sending a stereo send from a stereo track into a quad in an FX return in Cubase
