Patch 1.3.0a

Group Finder

 * Leaving a Group Finder group where all other members have disconnected will no longer cause players to be temporarily locked out of Group Finder.
 * Flashpoints and Operations will no longer occasionally reset and eject players who have recently used Group Finder for a replacement member.

PvP

 * Ballistic and Knockback effects no longer occasionally de-sync the character's location, which could cause characters to not interact properly with the world (such as being able to be hit by melee attacks when the character appeared to be out of range).
