Redactor regions in repeaters do not save content

Hi,

Something I've noticed as I've been transferring content to a new site is that when multiple redactor instances are created using a repeater then it does not always save the content of the editor. It doesn't even keep the content between POST requests.

Once the page has been saved and content re-entered it will save fine. There are no errors in the debug log, the update queries simply do not include the content from the redactor region. The plain text field retains the information fine. There are no console errors I can see either.

Possible triggers could be when making multiple repeater rows (EG, copying 3 FAQs would mean I would be clicking 'Add Another' 3 times then copying the content, then saving).

I've noticed this happening with redactor I and redactor II.
