Here is a list of the known issues for Book 10:

General

• Monster play: The "Enter Monster Play" button will be disabled (greyed out) when you first connect after Book 10 has gone live. Logging into a character that is at least level 10 will enable the button next time you're at the character selection screen.
• Recipes for certain ingredients required for some Reputation System recipes are not currently available
• Monster play: The Chest of Glain Vraig stays in the world for 10 to 15 seconds after a player opens it. If another player uses the opened chest before it respawns, it will consume the Key of Glain Vraig without giving the loot. To be safe, please wait until the chest respawns or during a time when the chest is not crowded. (added 8/20)

UI

• The mouse pointer may become lost if players are using mouse controls to steer and a dialog box appears onscreen
• The cost of sending items through mail does not visually update in the mail interface when a single item is changed to a stack of that item
• The "GO" option in the Stablemaster interface is highlighted even if the player has insufficient funds to travel
• The radar and quest tracker do not realign properly when "Reset UI All Scales" is selected

Quests

• If you currently have Book 8 - Chapter 5 underway and have defeated Mordirth, you will want to turn it in before the update goes live on August 20.
• When players have both the Spoiled Pie from Scary and Eggs for Holly Hornblower quests at the same time, picking up eggs registers as picking up pie
• When a quest is cancelled, the cooldown timer does not reset when the cooldown time is up
• In Troll session play, quest ring icons appear on the radar, but not on the landscape
• The monster play quest, "Troops to Tirith Rhaw" appears as available after it has been completed
• Player can be thrown to the other side of a closed gate during combat with Tarlug in the Castle of the Witch King
• In The Eye of Angmar instance, the gates leading to Amarthiel's Chamber close if Laerdan is defeated by Amarthiel.
• One of the Fel-talon in the Annuminas tombs will continue to re-spawn if players keep defeating it in its spawn location
• The Dark Hunters quest requires the killing of a second Tarkrip Captain, but only one can be found
• The monster play keep control icons are in some cases not displaying on the map
• One of the hotspots at Tirith Raw is not flipping properly
• In Garth Agarwen, standing in a certain spot near Ivar Bloodhand causes his intro actions to loop
• When launching Session Play in windowed mode, closing the game window during the Witch-king loading screen can cause the game to crash
• The Session Play Ranger Skill "Blood of the Dunedain" says it only heals 43, but actually heals 683
• The description for the Session Play Chicken skill Paranoia is the same as Feign Death
• Players who completed the "Black Incantations," "Black Challenge," "Black Lore," or "Black Imprecations" quests in Angmar will have to return to Lindir in Rivendell to re-take the quest(s) before defeating the Champions of Minas Caul, Minas Agar, Minas Maur, or Minas Angos, respectively.
