Lag in zones with a lot of caster NPCs resolved (it was a follow up on the last caster NPC fix, this one addressed a server-side memory management issue that was causing stuttering)
Lag in zones with a lot of players in close proximity fixed (Another server-side memory management issue to do with netcode that didn't scale well with a lot of position update packets)
Fix to the Feign Death exploit - you can no longer Alt+F4 after feign death to get your aggro permanently disabled upon return
