O have noticed that in the four games i have got that there is all ways a part missing. This includes this game of Lord of the rings journeys in middle earth. I am missing a strider number 1 card. Why is this . Not very good quality control. But all games are still fun to play even with missing part.
Missing parts from unopened games
Well, thats a bummer.
FFG, as far as I've heard has great customer support on issues like this. I recommend contacting them about it.
If its cards, I would recommend checking to make sure you didn't double sleeve on accident. Sometimes the cards stick together and I've accidentally put two cards in one sleeve. Luckily the cards are mostly in sequence so I'd start by looking at the Strider #2 card or if you remember the card that came before when you were unpacking.
That's weird. I've probably bought 100+ FFG products and the only issue I ever had was a couple of broken minis in an Imperial Assault expansion. That was more than likely a shipping issue.
Definitely reach out to Asmodee customer support to get a replacement. Although, I've heard they started having people return games with missing pieces to the retailer they purchased from. Hopefully they don't make you deal with that.
