Notes from today's hot fixes for the live servers:

 - Players who have completed the Know Thy Enemy quest will now be offered a second, repeatable quest by their realm’s Hero.

 - Players on Gaheris of level 48 or above may now speak with Sir Yvain in Camelot, Sinfjotli Sigmundarson in Jordheim, and Fionn mac Cumhaill in Tir na Nog to assist them in learning about their enemies.

 - The quest Know Thy Enemy is now available on Mordred.

 - The doppelganger parts left over from the Doppelganger Invasion can now be sold to merchants.
