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
botters too have been hit hard. I had accnt with friends list full of botters and were all online 20min ago. NOw, not one. It does apear to be a speed based banning (so i've been told) So if u must bot, go to a much longer game delay.
Dont believe me? just look at waiting lines
Edit: To answer ur question sov, I'd say that ur fuked. It does look like it happened in HUGE numbers. Here's just one link
they could b lieing n00blets and many have said they missed their chance but this link is one of MANY that say the same thing: Lots of 08 dupes on ladder
