Looking back through the SQL changes, this looks like it may also be needed for the old instancing system:
Code:
ALTER TABLE `zone` ADD column `insttype` tinyint (1) zerofill unsigned NOT NULL default '0';
And:
Code:
INSERT INTO variables VALUES ('curInstFlagNum', 2000, 'Determines what instance flag will be handed out next', '2008-09-05 04:46:47');
INSERT INTO variables VALUES ('dfltInstZflag',1000, 'Used to determine if a zone is instanced, must be 1000 or greater', '2008-09-05 04:46:47');
