Isle Royale Wreck Charter Adventure Scenery Issue

Pilots, my first scenery addition in MSFS (FS2020), Isle Royale Wreck Charter Adventure, seemed to have suffered slightly after several updates by Microsoft.  The wreck of the America is no longer visible beneath the surface.  However, it appears that the rest of the scenery is still working (at least for me and one other pilot who has tested it).  This includes the two marinas and the buoys where the wrecks are located - and of course, the lighthouses.   This does require that you include the free addons as described in the instructions. 

Eventually I'll get around to finding out what changes occurred so that I can fix the missing item for this flight, but it's still a fun charter flight for those with MSFS/FS2020.

Happy flying,

John
