[samigo-team] question about Data Discrepancy errors in Samigo

[Sam Ottenhoff]

If you receive a data discrepancy after question 50 of a 100 question
assessment with one submission allowed, you have to email your professor and
ask for a re-do.

Data discrepancy does not wipe out existing data; it wipes out your ability
to continue working on the assessment.
