Can someone remind me what the _1_0 at the end of Scene2_Slide4_Multichoice_1_0 means?

Thanks for the suggestion Jose! I think this would be pretty difficult to even replicate in our own LMS because it happens so rarely, but I'll see if I can figure out what triggered this strange result. It's almost like the module kept trying to tell the LMS that the person passed the question. Like when you tell your child to wash the dishes 15 times thinking they might not have heard you the first 14 times, but, in fact, they did hear you all 15 times.
