Dekaron SEA Dupe program???

while im playing dekaron sea this morning i was suddenly disconnected and i thought i was banned but when i relog my acct im surprised that my lvl rolled back and i think that there is someone making a dupe item coz if the GM would make an action like that they would've announced it right? im suspecting that someone had been able to crash the sever and make a dupe item.. can anyone confirm this? coz ive been searching for this TUT like forever just to learn that thing...

No usually GM's don't announce rollbacks cause people exploit them and dupe their items.

Crashing servers is really risky.... But it works ^^
How?
Go ask noobs who wanna share XD

Character data is automaticly saved every ~5 minutes OR when a character logs out.
When the server is shut down, the data doesn't save.
So if you give 1 character some items/money, if you know the server will be shut down in 1 minute, that character logs out, the items in his inventory saves, and you stay logged it, server shuts down, your info doesn't save, so you are rollbacked to when you had the items.

Due to this, the GMs don't announce maintenance anymore, so that this bug couldn't be abused.
