I created a simulation that i want my learners to take as an optional "Test Your Knowledge" type thing. I want the hints to be off and only give a score at the end. I don't want a wrong answer to cause the step to be repeated. I thought i had set all those things up but now you can only take the test one time; the second time it gets completely non-responsive. Would someone be able to look at the .story file and see what i might have done wrong?
