I noticed I didn't have any Supreme Flower recipes so I looked at the Expert Farmer in Hobbiton. Gold fire pipeweed field, and the processing recipe. That's all... so I go to Ered Luin. Same thing. In my list I have
and Fungo's pipeweed
plus gold fire
Maybe there is no flower recipe at all, but I can't be certain of that.
Anyway, I tend to make "Moria food" if an alt is of that level, so I was growing mint when I noticed this. Puzzling. Maybe an update is afoot, but I didn't notice anything in the release notes.
