Intended or Bug??? because if this is intended why even bother giving them those skills in the first place
Shipping is dependent on the host, just have your host choose the shipping skills and farmhands are free to choose any skill they want. Yes, it's a bit weird farmhands can still choose the skills, even if they don't work for them, but I'd say just enjoy the fact you can make the most out of the non-shipping skills.
What about selling to the stores? Has anyone science'd using those skills as a farmhand to sell direct?
That's also my question! If you are playing on one farm with one person who has taken the Rancher and the other person the Tiller skill, can the one with Rancher sell animal products and the other sell crops with this bonus. I'm talking about selling at the store, as it will not work with the chest and shipping as mentioned above.
