Has anyone seen the item below with SW10 when starting a route from a sub-assy?

Insert a sub-assy with routing parts into your top level.  Then start a route from this sub-assy, SW10 sends the sketches off to never-never land.

If the route is started from a part that was inserted into the top level the sketches appear to be fine.  See attached example.

The tees you see were supplied from the SW10 routing library, it's an xp 64 machine should that help.
