Jon,
This sounds like our "MN-937: Manual release => crash! bug" Jira.
I am attaching a patch courtesy of Nuno who reported this issue to us a
week ago.
With this patch, "instead of sending 0 to gradebook when the student
grade is null, it doesn't send it at all. This is in conformity with the
Mneme and Gradebook design where, a student that didn't submit the test
doesn't have a grade at all (instead of having 0 which would be
impossible to determine in GB if a student had 0 in test or didn't
attempt a submission at all!!)."
This patch will be part of our next public Mneme release.
Best,
Vivie
