I've read the wiki and it mentions that I can obtain Zenmai by finishing a quest given by Imperial Guardsman Linro. However, when I speak with him, he has no quests for me.
When I look at the list of quests assigned to me, I don't have "Chasing Zenmai" or the "Gain Zenmai" quest either.
I've double checked my hero list to make absolutely sure she wasn't listed. I thought I had Zenmai at one time, but maybe not. What am I missing here?
EDIT : I also have all 3 campaigns plus EotN.
