Update: Rift 1.2 Hotfix 6

GENERAL

 * The Defiant Rift quest, 'No New Taxes', should now progress properly when completing the Auricore Forerunners Rift.
 * Fixed a bug where players and groups who were locked to incomplete dungeons would be blocked from using LFG to queue for another specific dungeon (or from using the LFG Quest page).
 * LFG: Fixed a bug with LFG Random dungeons not ignoring lockouts - you should once again be able to enter a dungeon you already have a lockout for through the Random Dungeon queue.
 * Low-level characters reported for spam are now aggressively filtered.
 * Hopefully fixed a bug where the camera would spin around in situations with lots of mouse input, for reals and truly.
