["unknown column" "missing table" "duplicate column" error / sql problems / SQLDriverLogFile < answer on 1st post of 1st page]

Simply run this query in the characters database:

DROP TABLE IF EXISTS `pool_quest_save`;

CREATE TABLE `pool_quest_save` (

  `pool_id` int(10) unsigned NOT NULL DEFAULT '0',

  `quest_id` int(10) unsigned NOT NULL DEFAULT '0',

  PRIMARY KEY (`pool_id`,`quest_id`)

) ENGINE=InnoDB DEFAULT CHARSET=utf8;

Which we can find in the 3.3.5 sql updates folder; found it in 10 seconds ^^
