I've reported this before, but I can't recall if IRs should be submitted or if an email to Admin is the route to take when a set is erroneously shown as completed on the "Sets in this collection that are complete" while the Collection Summary page reflects the actual percentage (less than complete). Which is the appropriate option?
“Aslan didn't tell Pole what would happen. He only told her what to do. That fellow will be the death of us once he's up, I shouldn't wonder. But that doesn't let us off following the signs.” - Puddleglum in The Silver Chair by C. S. Lewis
