Problem resolved.

I recently bought a 1k small vault and I bank all my stuff. I remember the valuable stuff i still have there was 128 wood, a golden sword, and a diamond pick axe. So I venture off somewheres and decided to go back to my vault and for some reason it says I did not bought a vault. I was confuse and I check my MT credits and it was the same but I lost all my items that I stored in the vault. I don't know what's going on.
