The problem with Gen Z event #18.2 has NOT been fixed yet.  You can run the event but it wouldn't count. 

Now that event totals drop every time they eliminate another Hub round, I came up with a simple way to make my #'s match.   I subtract ALL of the Round 1-6 events and then add back the difference between that # and the "total events" # on the profile page.  That's the # of Round Hub events that you ran.
