On jvwiki, it looks like the only mentor there was removed from the list: https://jv.wikipedia.org/w/index.php?title=M%C3%A9dhiaWiki%3AGrowthMentors.json&diff=1619084&oldid=1601043
Subsequently, we get an error when attempting to reassign the mentees to a new mentor, since there isn't one. How should we handle this type of situation?
