1) open a deck in the deck editor
2) make a modification (e.g. change the count of a card in the deck)
3) Save the deck
4) Exit the editor
Note: it reports that there are usaved changes and requires you to save it again.

The problem is here:
DeckBuilderWindow.xaml.cs: DeckBuilderWindow.SaveAs()

try
{
Deck.Save(sfd.FileName);
deckFilename = sfd.FileName;
}

This block should probably set this.unsaved = false;

The same problem exists in DeckBuilderWindow.Save()
