Firstly, although our patterns are extensively checked we do occasionally find an error. If errors are found we issue updates via email, so if it’s been a while since you purchased this pattern please double check that you have the most up to date version by comparing the version number in the footer to that listed on the product page on our website.If you've updated the pattern and there still seems to be an issue please do contact us at support@ysolda.com so we can have our tech editor check it and issue an update if necessary. We'd rather know so that we can fix it for everyone!
