title: Magento CE Customer Groups Changing Not Saving
body: <p>In the Magento CE Admin Panel, I go to Customer > Manage Customers. </p>
  
  <p>Then tick the select box in the customer row that I want to assign to a group, then in the 'actions' dropdown above I select 'Assign to a customer group' then select the group then click 'Submit'. </p>
  
  <p>I then get a 'Total of 1 record(s) were updated' message displayed above but the problem is that my customer group still has not been updated/saved! No errors but not updating!</p>
  
  <p>I even tried editing the customer group by editing the customer's account information 'Group' setting but same result?!</p>
  
  <p>I have no idea how to resolve this...</p>
  
  <p>Has anyone else had this issue?</p>
  
  <p>Thanks</p>
