Yep, I have the same thing here.
1. Edit the category(woocommerce product category), add all the cool stuff. (thanks! awesome plugin)
2. Save it and it displays great! All shortcodes work too.
3. Attempt to edit and update the category content – and All the Content vanishes.. if you dn’t have the original content – make sure to NOT! click on save.. because that content will just disappear forever. – clicking off the page and going to the website-view to copy it all and then re-editing with all the images/text/code is needed.
I’m using:
Wordpress Version 3.7.1
latest Woocommerce
The maya theme by ‘yithemes’ – this is their demo site:

Anything you have to stop this form happening would be excellent.
Thanks!
