I had already completed the USS Constitution when I started the Gilded Grasshopper quest. As a result I am unable to get the gelded grasshopper on the roof of Faneuil Hall because the USS Constitution is on the roof. Does anybody have a work around for it? I do not have a save that is before completing the USS Constitution mission so loading a earlier save is not a option.

The USS Constitution crashes into the roof of the tall metal building next to Fanueil Hall. Fanueil Hall is the small red brick building with the super mutants and bonfire in front of it, next to the tall building the ship crashed into. So it shouldn't effect getting the gilded grasshopper.

^ Good workaround there.

Could of links that might help.
