The issue with the Summer Event has been reported on the live servers already, but the Fellowship one is new. We have reported that now :)

So, it is intended, that the Fellowship Event (and now also Soccer) have a new achievement, cause the event mechanic has been changed. The issue with the Summer Event is still going to be fixed though.
