That's not confirmed to just Stephanie's Poses. It happens with V3 and V4 as well. Sometimes m4. Just wish I knew what it was to isolate it.

Yeah I see that when you apply one of the DAZ "Stephanie 4" poses, it causes any conformed clothing to become "stuck" in the previous pose.  I haven't figured out exactly what is in the poses that causes this, but to work around it, pick any one conformer and re-conform it to V4 and everything will pop onto the figure.  I don't know what will happen with multiple figures in the scene.  Since it appears to be a problem with the pose files themselves (other poses of mine work fine) I'm looking at them to see if there is a permanent fix to get rid of this problem. 

Moving the V4 figure a little bit and undoing also seems to make the clothing pop onto the figure...
