I don't know if it's a bug but when I do a search in Warhammer Invasion like : Rules Text contains skaven
The result doesn't show all the cards with the term. I don't have for exemple Clan Moulder's Elite or Warp Lightning Cannon. I think it's because there are other term before.

Ok it's not a bug, I just understand, I search a trait and there is a function for that.

Sorry

Yep, those are traits. I just checked the pictures and you are right... maybe people would expect Rules Text to also include the traits. I've duly noted this... :) If it comes up again and proves to be confusing, maybe I'll change it so that the traits also appear in the rules text, so you would find those cards as well...
