Survey disappears before I can participate.

This is the second time I've been asked to participate in a survey, which I'm happy to do. Unfortunately, the last two surveys have disappeared before I was able to participate. One just disappeared after I answered Yes to participating. Today, after agreeing to participate, it asked me if I was primarily a DM, Player, or A mix of both. I answered and the survey disappeared. 

Same.

Same here twice yesterday and today. First time with my primary GM account and second time while I was logged in with my dummy player account. Survey disappeared as soon as I had clicked on the check box 'GM' respectively 'GM & Player'.
