This was done by some sort of team hackers or whatever.
The old characters became ladder and the ladder became non ladder.
Thus when the old ones converted to ladder they made a new game dropping all the NON ladder items in a game made by a ladder char. Waited for the bug to fix itself making their ladder cahrs get there ladder status back. Then they joined the game abd grabbed all the non ladder items. The Economy is now fucked. I myself xfered over a shit load of items.
thats bad. Unless some kind of rollback or some shit the ladder economy is FUCKED. Don't believe that? here's the link
