Numbas SCORM not returning results to Blackboard Grade Centre

[libvlet]

Hello,

We have a Numbas package deployed in Blackboard LMS SP12, with the Rustici Scorm engine 2013.0.1002957. 

The Students completed the assessment and were returned scores on screen however the scores are not being returned to the Blackboard Grade Centre - the attempts are being listed as "Attempt in progress". 

When we inspect the attempts they are listed as incomplete:

Learning Object Name	Total Time	Status	Scaled Score	Learner Response	Result
SOEE5154M NUMBAS Exam 14/10/2013	0 seconds	incomplete	0%	N/A	N/A
Exam	0 seconds	incomplete	0%	N/A	N/A

The Academic previously deployed a Numbas package in September which did appear to work correctly and grades can be seen in the Blackboard Grade Centre - the only difference in the two deployments (that I can see) was that the package showing the problem was set to one attempt only.

I tried modifying that setting on the item in Blackboard ex post facto however as I suspected, it made no difference.

Has anyone experienced a similar issue with Blackboard / Numbas deployments and could advise Blackboard SP12 for deploying Numbas packages? I'm assuming the data for the attempts in progress is not readily available?

I've posted a version of this question on the numbas github repository as an issue.

Regards,
