All answers are removed in the workbooks

Hi Support,

This morning we get an e-mail from one of our students. He was tell us that he don't see any given answers on the site from different units. If we take a look at the users workbooks (for example Wesley Koolen) we don't see any answers anymore. We're almost finished with the course, so it is important that we have the answers from the student.

Can you please take a look at this issue?

Thanks,
Ton
