Thanks for at least trying to bring it to our attention Yona. While not all items are going to be given augment slots due to special cases like this(it's quite possible this may even need an augment slot - I'll have to find out who designed it and either get a yes/no from them or Wiz), it's definitely a good idea to bring up items with missing augments. It doesn't hurt anything for them to be dismissed as intended, but with several thousand items in the database and the fact these augment slots were added by hand, there's a good chance some items are missing them.
Commander's Sigil from Fearstone, for example, was missing an augment slot because of the unusual name for the item.
