Out of interest, I tried installing version 2.1.2 over the top of the latest version and it appeared to install without any issues.

I tested SCORM again but unfortunately I was still getting the same logs in the debug window for MCQs.

Decided to go back another version to 2.1.1 and I think this one is recording the cmi.interactions correctly. Need to do some further testing with the LMS but it's looking good so far!
