void MySQL_UpdateBan(BanData bandata)
        {
            Sqlite.Insert(Core.Database.Sql.Builder.Append("UPDATE EnhancedBanSystem SET `steamid`= @1, `name`= @2, `ip`= @3,`reason`= @4,`source`=@5, `game`= @6, `platform`= @7,`server`= @8, `expire`= @9 WHERE `id` = @0", bandata.id, bandata.steamid, bandata.name, bandata.ip, bandata.reason, bandata.source, bandata.game, bandata.platform, bandata.server, (int)bandata.expire), Sqlite_conn);
        }​

Should be of course:

        void MySQL_UpdateBan(BanData bandata)
        {
            Sql.Insert(Core.Database.Sql.Builder.Append("UPDATE EnhancedBanSystem SET `steamid`= @1, `name`= @2, `ip`= @3,`reason`= @4,`source`=@5, `game`= @6, `platform`= @7,`server`= @8, `expire`= @9 WHERE `id` = @0", bandata.id, bandata.steamid, bandata.name, bandata.ip, bandata.reason, bandata.source, bandata.game, bandata.platform, bandata.server, (int)bandata.expire), Sqlite_conn);
        }

I bet there another of these. Can you please check.
