There will be a patch today that contains the following fixes and changes:

New

New client software

New fast cast 65% mounts on the NoScrub's vendor. These have half the cast time of the other mounts. If you already bought one of these before the stats were changed, yours will now have the new stats. Rock Griffon, Glossy Black Manticore, Heroes Ghost Bat. The 3 Thundercat mounts will be replaced by newer models with the fast cast and speed increase.

All of the older costumes with either none or basic stats have been updated with full stats and card slots.

ALL head costumes now have a card slot.

ALL body costumes now have a card slot.

ALL full body costumes now have 3 card slots.

Battlefield Points Potion added to the NoScrub's Vendor.

Reduced the cost of the Skill Reset potion.

Bugs

Battlefields timers hopefully fixed but needs testing.

Level 65 gear has temporarily been set to level 60 so you can strengthen/enchant again. Stats remain the same.

Some fixes to costumes with incorrect stats or missing slots.

The unfinished raid boss Lost Mysterion will be disabled, it shouldn't have been spawning in Night Forest. (Thanks for pointing it out guys).
