2. Achievement/Conquest Window Doesn’t Checkmark Boxes (I.E. GR55 with 6 sets)
   The Achievement/Conquest Window is slow to update and at times will not reflect say a GR clear with the required set. It will update sometime but it is still considered complete and if you meet the requirements for the achievement/conquest, it will still finish even if the check boxes are not updated.

Known issue with achievements, Please see stickies. They are SLOW to mark of checkboxes at times. However once all the requirements are done (checked or not checked yet), the achievement will fire off.
