I would also like to note, that when I was trading alexandrite I would Disconnect from the game constantly. I was trying to trade all 30k alex as my last step and was disconnected 10+ times before I could trade all 30,000. As I would move it over from mule to main and/or trade to the NPC I would get disconnected over and over again, It took me over an hour to trade all 30,000 alexandrite just to go to white gate and be handed the incorrect weapon.
