The first time this happened was when I was at my friend's house, where I crafted a weapon that costed me all my mist. I log out, and my friend logs in to discover all his mist is gone.
This occurs a second time, when I crafted another weapon. I log into another account that isn't an alt, it is a different account that has a different username and password. I discover all the mist on the account is gone. However, when I tried a differnt computer, I discovered that my mist came back, and that it came back to BOTH accounts. I then crafted another weapon on the 1st account with the second account's mist energy.
So my question is, is the mist level saved to a computer, or is this a bug?
You should not admit to 'stealing' mist from another account :P
