Auto Register does not work on MoopleDEV for a weird reason

[SugoiWoah]

It said there was something wrong with it and that there's a column missing, when in fact it should be there:

SEVERE: Something bad with autoregister.
com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException: Unknown column 'lastknownip' in 'field list'

mysql> ALTER TABLE `accounts` ADD COLUMN `lastknownip` VARCHAR(30) NOT NULL DEFAULT '' AFTER `macs`;
ERROR 1060 (42S21): Duplicate column name 'lastknownip'

What can ever be the issue here?
Thank you in advance

Is there a column named "lastknownip" inside the "accounts" table?
