This is the situation: after many changes and a server upgrade made to improve many fields of the site the Quiz started to fail its duties every week or two. (Instead of the normal random glitches that we were able to fix once for all)
The tech guy noticed that there's a glitch that corrupt tables where the answers are compared.
As you know there's a way to reload the Quiz, but this solves the problem only temporarily until a new problem appears.
Don't worry the Quiz is still there and still (half) working, and we would like to have it back too. It's just disabled, I saw that this was becoming a source of frustration and difficult to manage so we decided to leave it disabled.
I hope we will find a solution or we should start thinking other alternatives.
That's pretty much all I know for now
