Quest ID 13411 Hellfire Fortifications DK version (http://www.wowhead.com/quest=13411/hellfire-fortifications) is missing the RequestItemText: Return to me after you have helped capture each fort!

In quest ID 13409 & daily quest ID: 10110, that text exists already. SQL query to compare the 3 quests:

SELECT `RequestItemsText` FROM `quest_template` WHERE `Id` IN (10110, 13409, 13411);

RequestItemsText
-------------------------------------------------------
Return to me after you have helped capture each fort!
Return to me after you have helped capture each fort!
(NULL)

The Alliance DKs have already got the RequestItemsText for all 3 quests. Query to show those 3 quests:

SELECT `RequestItemsText` FROM `quest_template` WHERE `Id` IN (10106, 13408, 13410);

RequestItemsText
---------------------------------------------------------------------------
$N, return to me when you have aided in the capture of each of the forts!
$N, return to me when you have aided in the capture of each of the forts!
$N, return to me when you have aided in the capture of each of the forts!

Solution:

UPDATE `quest_template` SET `RequestItemsText`="Return to me after you have helped capture each fort!" WHERE `Id`=13411;

Edit: solution tested, works as intended. Unless you have any objections, write-up and close.
