First, I think you should do backup, or at least have a test server to test it on.
2nd, That didn't happen before, right?
For a working script, i never tried it, cause you can ban easy with 1 script thru the SQL.
Btw, Alladrious/LPH added some more script if u have issues. So go and check it. ( It's always usefull to read the replys, when u watch some of releases, they ussualy talk about Errors there.
Btw, you posted here, plus in the Shaiya Private Server Section. Either Shaiya/Shaiya Private Server are for questions. Shaiya Development is just for releases.
On there.
