Sounds pretty dumb, but I had a go at the crew creator, made a 10T list which included Yin, but when it came to giving her upgrades, smoke grenades didn't show.
I'm not saying I wanted smoke grenades on Yin, but the card says "non-leader, rare 1" so surely she must be allowed to use smoke grenades, but the crew creator is being a little funny.
Anything i'm missing?
