When users save their survey, everything seems to be working fine. They get an email that lets them back into the survey. They must answer the security question to verify their token. After that, they are taken to the first page of the survey and all the answers in the first group they once had filled are defaulted. However if they go to the next group of answers, they are saved and intact. Also, the progress index is restarted although the following pages have filled answers.
The survey was set up group by group, uses sessions and cookies, uses tokens instead of username and password.
