Update: Rift 1.5 Hotfix 9

RIFTS AND INVASIONS

 * Rifts will now drop Sourceshards and Inscribed Sourcestones based on their opened level, preventing some Rifts opened with the Planar Attunement lures from dropping incorrectly low-level Sourceshard items.
 * Due to the above change, Inscribed Sourcestones now drop from level 40+ Rifts (lowered from level 45+).
 * Zone events have been updated to allow for any Rift or Invasion of a specified planar type to count toward the event objectives.
 * Increased the rate at which Invasions scale in high-level zones; the Invasions should be somewhat beefier when the zones are highly populated.

GENERAL

 * Hammerknell: Taught certain NPCs why killstealing is bad, to fix a case where raids could kill Akylios without getting credit.
 * Hammerknell: Grugonim: Corrosive Bile and Unstable Spores have had their projectile speeds reduced, damage lowered, time between uses increased, and a new warning message.
 * Fixed the Mathosian version of the Exponent's Hauberk so it looks like the version everyone else got!
 * The Harbinger of Regulos companion pet item is now tradable.
 * Nightblade: Blackout: No longer causes spell-based attacks to miss. Duration has been reduced to 5 seconds from 6 seconds.
 * Gloamwood: A Woman Scorned: Seriously, the Hag's Curse shouldn't get stuck on people anymore.
 * Quests in instances containing cross-shard LFG members (ex: dungeons) now work properly with quests that require you to use a quest item in a specific location.
 * Dark Pulsing Crystals are now available for purchase with Inscribed Sourcestone.
 * Fixed a bug with selecting targets for abilities cast through the /cast slash command.

WORLD EVENT

 * Slightly reduced the difficulty of the first unstable stage of Ashes of History Rifts, 'Gold Tenders' and 'Forged Menace'.
 * The World Event quest sticky has less blank space around the on-screen text.

CLIENT

 * The client should now be able to log back in properly after recovering from a crash!
