While my editors and I do our best to check and double check ... and triple check! everything, we're not perfect. If an error is discovered though, patterns are always revised and updated right away. And if an error is major - enough to throw you off or mess up your project, you'll receive a notification by email if you purchased a download from this website or by pm if you bought it on Ravelry.
A pattern might also be revised and updated for a variety of other reasons - to correct a minor typo, to tweak the wording if it might make things a bit clearer, or to add a new photo if I happen to get a better shot.
Most patterns will have a version number at the bottom of the first page, such as, v.1.18.12, which is reflective of the date (month.day.year) when the pattern was last updated.
You may get the latest version at any time by clicking on your original pattern link,
or by requesting an update: firstname.lastname@example.org.

Patterns downloaded before 2/3/12 - the left and right front charts on your Olafsdottir pattern were symmetrical with regard to the slanted flower and ribbon charts. Not that there's anything wrong with symmetry ... however I had knit mine with all the slants going to the right and so patterns have updated to reflect that intention.
Patterns downloaded before 1/12/12 - Right Pocket, Waist shaping - read, "place held sweater sts onto LH needle and join, k3 (3, 3, 4, 4, 5) ... " Corrected it now reads, " ... join, k0 (1, 1, 2, 2, 3) " for more symmetrical dart placement.
