Error message when I click on an adult member in Scoutbook roster

I get an error message when I click on adult member (removed by Moderator) in the Scoutbook roster. I tried 5 or 6 times tonight with the same error message each time.

@CharlesMcDonald This is a known bug. On the page where you get the whoops error, just reload the page (SHIFT + reload), and that should get you past the error message.
