Unsure if this is a bug or not.. but i'm trying to purchase Wheat Seeds from Ahr and it's not allowing me to purchase any..

This quest.

click the name not the icon of the seed

that not bug, in that main quest you need deliver that seed to owner that from you buy it before.

Ohh okay. I needed to click the name didnt realize I was clicking the icon. Before this quest you deliver something to Ahr. I've already did that.. but it was me not clicking the name.
