Has anyone ever run into an order that wouldn't update? This is in a 1.3.9h cart where editing orders has not been a problem. This one very large order is now missing the name and address info after attempting to update. After hitting the update button, the url remains the same but the screen refreshes and shows the home page of the site. The quantities do not update. There has to be over 50 line items with a few attributes.

The order was entered in with logon as customer which also hasn't been an issue before. Site has been up and working since 2012 with no issues.

I've been trying to get them to upgrade so in the end that's what we'll probably have to do and hope the problem goes away. Just wondering if anyone had had this happen to them.
