This fix a very old bug where the client would not apply spell modifiers like talents when a player is reconnecting while having its character still connected in-game.

• Login on a warlock character.
• Take the improved 5/5 corruption talent which makes corruption spell instant cast.
• .save
• Open another client, connect on same character while having the character still in-game on the first client
• Try to cast corruption while moving.

Without this fix, you won't be able to cast it while moving, despite having the 5/5 talent.

Another related issue to this particular situation: If you are on a fly path when reconnecting, you will drop to the ground.

On my end I fixed it by kicking the player before resetting the session state ( if (!m_session->RequestNewSocket(this))) if is he is on a flypath as I don't have much time to find the root cause right now.
