end-user gets stuck, corrupt suspend data

Wow -- thanks for thinking up this solution, which is a lot better than making the user retake the course!

I have occasionally and very upsettingly have this happen to users in my client's LMS, with no solution other than to make them retake the course.   The only surefire way I have found to avoid it, which was given on a related thread, was never to allow slides to have "Resumed Saved State" or "Automatically Decide" in the Slide Properties/When Revisiting option -- they should always be set to "Reset to Initial State".

I don't think, however, I've applied this to Quiz questions because I haven't encountered it with them.  I'm afraid it would mess up the Review Quiz feature if that were being used.

It's also possible that this issue only happens in the "Classic" player and not the Modern, but I'm not sure...
