In IE8 on Windows XP, went to http://grouppatternlanguage.org/wagn/testing_pattern and made it a Pattern and clicked "Submit" 

The card was created, and i got the "Create Successful! Redirecting..." message but it didn't redirect.

After reloading, i got the adding interface when i clicked on "ADD +HEART", typed in some text and clicked "Submit" and the card was created, but with no content in it.

Even after reloading, double clicking in the "--" doesn't do anything. (Double-clicking in form-included cards with content works.)

Clicking on Edit for the whole pattern goes to edit mode, and when i click Save it seems as if it's working, but any content entered is not saved, and if content is entered in a card that didn't exist, it is not created.

No related Hoptoad errors.
