If you insert a component/group inside other component/group and rotate the inner comp/group and scale the outer comp/group it will skew the inner group. If you save the inner group with this skewed scale into an external file and assume that scale (SU asks what you want to do) you'll get some funky component. When you reload it into the model, that funky component will be scaled and skewed again, becoming even funkier. That can go on and on until the funkiest unlimited possibility.
