Moving the entire layout, especially after it has already been routed, may result is some changes to the layout. If you have selected the entire layout traces should move along with the selection. Look to the right side of you screen and press the green button. This toggles selection to all on. This means you should be able to select all objects on the layout. Now drag a box around the entire layout and try to move the selection. If you still have trouble you can send your file to firstname.lastname@example.org
for review. If we can verify an issue we will report it to development.
