m0useanswered grow question a year ago its been happening to lots of people.
Some saw deleting the week then reposing helps. Other just retry over and over.
When I update it always messes up the images and I need to remove a few and add them back in. It has yet to mess up the nutrients or the text description of the week for me, but this is a common things as well from what I have been hearing. One time though the update just kepy spnning and nothing uploaded. it was really annoying. ALWAYS make a copy of your weekly entry do if it fails you can hit paste on the text part.
Best thing you can do is explain your frustrations to GD by the contact us from and let me know.
This have messed up the site bad with the introduction of anti-spam filters and trying to control the trolls who plague it.
Good Luck!
