I can't get any friendship letters anymore...
Anybody else experiencing this kind of behavior?
Or is it intended to be limited to a certain number daily?
My friend list is full.
And the event does not state anywhere that you need friends to get friendship letters.
Only that you need to duel standard or legendary duelists on the world map.
So I should be able to get them everytime I finish a duel...
But that is not the case.
I do not get any friendship letters from any kind of duel...
