Update: Rift 1.5 Hotfix 1

GENERAL

 * You can once again enter Runic Descent!
 * Added a variety of fix cases for the Chronicles of Attunement where players could get into a stuck situation in the event.
 * Swift Murdantix Spawn mounts are once again epic mount speed.
 * The Swift Murdantix Spawn named item will no longer drop in the Hammerknell Chronicle. A renamed version, the Ancient Murdantix Spawn, will drop instead.
 * Corrected World Event merchants and Rare Planar Goods merchants still requiring Crystal Sourcestone to purchase items. These should now all use Inscribed Sourcestone.
 * Special in-game mail sent from the Trion system or NPCs will no longer be auto-deleted when using the Take All button. Auction mails will still be deleted when taking all attachments.

UI/SETTINGS

 * Fixed the chat message for posts on the guild wall that would break from certain characters. In other words, <3 all up over the place!
 * Fixed some text fields (most notoriously, inventory search) holding keyboard focus longer than intended.
 * If you try to purchase an item but don't have the items necessary to buy it, the error message will now tell you what you're missing.

CLIENT

 * Several client crash case fixes, including when combining chat windows and one involving artifact collections.

The following additional notes were included in the EU 1.5 Hotfix #1 and will be going out to the NA shards during an update tomorrow morning, to bring the two regions back in sync:

VETERAN REWARDS

 * Veteran Reward achievements now show your current progress.
 * Jarvis and Cadbury - the Veteran Reward merchants - are now friendly to both Defiant and Guardian players.
 * Veteran Reward merchants and mailboxes are no longer automatically added to the Ability Binder; you'll have to click them in your inventory to learn the summon ability. This should make it easier to figure out where they went when you claim them from the reward mail!

MARKSMAN

 * Electrified Munitions, Silver Tip Munitions: Removed the internal cooldown when using single-target ranged weapon attacks. The 1-second internal cooldown remains for area of effect ranged weapon attacks. These abilities no longer trigger from ranged auto-attacks.

GENERAL

 * Players will now be notified in the chat window when raid leader promotions happen in a raid.
 * Fixed a runtime error that was preventing the game from launching for some people.
 * Quest: Damming the Stream has a more accurate failure message on the horn.

ITEMS

 * Fixed the 'Take All' mailbox button saying your inventory was full when some of the received items could be merged into an existing inventory stack.
 * Dragon Quintessences can now be purchased via either Dragon Tears or Planarite in Sanctum and Meridian.
