Ok, so I figured out a fix. In the file moode/lib/gradelib.php, in the function named grade_update, down near the end of the function is the code:

if (empty($g['userid']) or ($k != $g['userid'])) {
 debugging('Incorrect grade array index, must be user id! Grade
 ignored.');

 if (!empty($g['userid']) and ($k != $g['userid'])) {
 debugging('Reindexing!');
 if (array_key_exists($g['userid'], $grades)) {
 debugging('Entry in $grades exists for uid ' . $g['userid']);
 }
 else {
 $grades[$g['userid']] = $g;
 }
 }

Once you've done that, then go to the gradebook and select Categories and items from the drop-down menu:


Then, click the Synchronize legacy grades button:
