Well i will spill the beans on a method that might work.
you can mimic the rollback that occurs during the shaking of Oryx's castle and use that to create the same event but make it happen while leaving vault coded using c# a dll plugin for Krelay
so basically when you send the hello packet you have to change obf1 to a special key and change the game id
accountinuse+moddedhellopacket=(rollback=dupe)
if you figure it out skype me "theflyingepic"
that's pretty much i am doing
Simply just sending a packet that rollbacks back your character but without sending a pass amount of packets
