I am not sure which version the change happened in but I just finished comparing my upgraded ZC store to a brand new install and noticed that this line
Code:
INSERT INTO `zones` VALUES (50, 223, 'PW', 'Palau');
has been changed to
Code:
INSERT INTO `zones` VALUES (50, 163, 'PW', 'Palau');
in 1.3.6

My upgrade did not reflect this change.

Thanks!
