Update: Hotfix 20

RIVER OF SOULS

 * River of Souls quests that have been completed may be turned in to Bourlana in Meridian and Brendnall in Sanctum.
 * Quest items for Tools of Destruction and Exorcising Evil will continue to drop for any players with the active quests.
 * Players are no longer offered the quest “Bolstering the Defense” by faction invaders.
 * Otherworldly Sourcestone will no longer drop from death invaders or colossi.

GENERAL

 * Major zone events should fire off more often and the mythical purple zone event currencies should rain from the sky! Okay, maybe not rain - but they'll be more common than they have been recently.
 * Scarwood Reach: Sealing the Portal: The portal at the back of the Sagespire should be much more active now.
 * Reporting spam for an offline character will no longer fail.
 * Fixed a cosmetic issue causing the UI to report negative damage when damage preventing effects “attempted” to prevent more than 100% of incoming damage.* In those situations, true damage taken was (and still is) 0.
