Not sure if this is a bug or deliberate. Or even how to report it if it is the former.
I'm using Moodle 2.8. The learners are all in the same group. The questions are cloze questions using the :NM: tag.
If requiring a comma as decimal marker in the answer (as opposed to a full stop), the quiz does not show hints (using interactive with multiple attempts). The quiz instead regards the use of the comma as "incomplete" even though it will mark this answer as correct or incorrect on deferred feedback.
Is there a way to fix this?
