I figured it out. My character is buggy.
All dishes made by me with the affinity of mining, got the affinity of beverages. Or, for example, food with an affinity is the strength of a body; instead, it acquired an affinity for alchemy.
I even bought food from a veteran of the culinary business at the market, I asked him to make me a mining affinity. But having eaten food, I got again an affinity for beverages.
What should I do in this case? Who had that?
Is this a reason to contact the developers?
