Saving Progress of Video when Exiting Course

I've had this workaround in place for a series of several dozen video-based trainings for almost a year. It's not the greatest, but it is functional (when people pay attention and don't just click the course window closed.)

I now have an issue where this workaround does not work. Clicking on the on-screen button to jump to my "Your Progress has been Saved" slide only half-loads the slide (the player settings change) and no progress is saved. It is impacting new projects and projects which I published last year.  

I worked with my team internally and we were able to determine that it is related to this type of error: https://community.articulate.com/discussions/articulate-storyline/articulate-could-not-fi[…]e-and-articulate-actionator-exejavascript-is-not-defined 

Thank you in advance - I'm happy to send packages or links to these in Articulate Review. 

(EDIT: I was never able to isolate what the specific issue was, but I was able to publish functioning packages after rolling back to v3.46.23620.0 - I will submit a bug report).
