I've found this list of cards in the Westeros decks:

https://github.com/mrhappyasthma/GoT-Board-Game/wiki/Westeros-Cards-Reference-Sheet

If this is accurate, there should be at most one "Last Days of Summer" event in, say, Deck II, unless the deck has been reshuffled.

I've just encountered a 2nd "Last days of Summer" event from the same deck without a reshuffle in game #109245. So, if I'm not mistaken, either the list must be wrong or there is a bug in the Westeros decks implementation.

Best,

Alex

Ah, thanks! I checked the events by means of the review game feature but the reshuffle is not mentioned there (it just shows the CoK event that was drawn after the reshuffle). Will check the game log next time
