Satanclaus: To any that have the Collect'em all quest completed: do the Poor F-Ing Infantry stack or are they different cards? Started my third playthrough in 1.06, finished in 1.07 and STILL haven't completed the quest. According to gwentcards.com I'm now at 196 cards as well (as Kerrovitarr mentioned) and I have 2 PFI stacking and two more out of the stack. everything else is right on the money according to the guide.

Unrelated trivia: Have a screenshot where someone I was playing had two Triss cards in their deck o_O

Xerafex: I also have the same problem where two of my PFI cards stack and two don't. However, as far as i know there should only be 3 in the game. I did also contact CD Project about that, some time ago and they said that they would look into it. However, I did complete the quest in 1.06 and also received the achievement back then.

I did also play against one player who used 2 Dandelion cards in the same round, at least their effect did not stack.
