Well, this is embarassing but serves me right for not reading the log
Code:
Required SQL:
ALTER TABLE `zone` ADD `cancombat` tinyint(4) NOT NULL default '1';
UPDATE `zone` SET `cancombat` = 0 WHERE short_name = 'nexus';
UPDATE `zone` SET `cancombat` = 0 WHERE short_name = 'poknowledge';
UPDATE `zone` SET `cancombat` = 0 WHERE short_name = 'potranquility';
That solved the problem - I'm sorry to trouble you guys with this problem. Next time I will hopefully try harder before running my mouth.
