Unplayable events
Facing the unplayable game modes , actually in capped legends events after completing chapter 2 the next day the game mode are unplayable in this events in both the chapters and this is not the first...
Thats how they designed it. Once you got 3 stars there you can only claim the daily pack.
Unfortunately EA doesn't give any guides for their events so we figure those things out by reading carefully and trial and error
