Lost all my playerdata, feeling good

[TWolfWD]

What I can do is replace your new account data with the old account data, but if I do that you'd lose anything new you've found that isn't in a chest. What I recommend you do is store everything in a chest next time you log off (not an ender chest, that will be lost as well), and post here to say you've done so. Once you have, I will go ahead and replace your new account's inventory with the old accounts inventory, and we'll see what that gets back for you.
