@Dylan Their may be a issue the way vB Activity reads Quizzes created and Quizzes completed, as seen in the following image, I have completed more than 1 Quiz and it shows 0, and I have not created any Quizzes and it shows I created 1.
I have it fixed, it will be in the next release. The file that completes the quiz entry had code giving points to creating a quiz instead of completing a quiz. The counts are correct on here now.
