In some cases, added gradebook events that are assigned to a category will get moved back into the uncategorized category as soon as the teacher clicks on the view or edit tabs. Any grades previously given to those events will be lost.

Looking at the grade_item table, it appears that the gradebook events are being deleted from the table. If you then go to the add event or category tabs, the added items are re-inserted.

The problem is in lib.php, in grade_get_grades(). If there is an item that was deleted, it is supposed to be removed from the grade_item table, but it is incorrectly removing items matching $mods->modid instead of $mod->modid. The result is that anything with a modid of 0 (added events) gets deleted, and the deleted assignment/quiz/whatever doesn't ever get deleted.
