I was transfering items from my old account to my new one via mailbox. I didn't know it wouldn't show up on my gold server (items being from old silver server). Now I can't get my items. I tried to fix this by transfering my gold into the silver server on the new account but I checked the mailbox and my character and nothing was there. I sent a lot of items and it would be a shame to lose them all.. please help!
