Minecraft: villagers do not change profession?

In my village I made a dweller a book merchant. But now I want to make him an armor dealer so I have dismantled the lectern and have put him a furnace but he does not change his profession.

You still have to interact with the smelting furnace.

Okey, I'll try it.

The smelting furnace is now melting gold and he still does not change his job: /

It can take a while. If not reassure yourself that there are no other work blocks nearby and build another stove.

Okey, I'll do it.

Sure you've broken down the RIGHT Reading Desk? If there are several, then dismantle everyone.
It takes a while to lose his old job. Sometimes it makes a mistake, and it does not lose it anymore, then just reloggen or Reload the area.

I had only one thing in my world. But he has to lose him first so his job and then I place only because block? Did not break down the lectern and have placed directly because of melting furnace.

That's how I used to do it. But should not make a difference, but give it a try.

Okey, I'll do it. I have a small village and I still have a farm whose job he could accept. The house of the resident of the armor blacksmith is but I think far enough away. Have him locked up in there dadrin so he does not come too close to the farm. Is that correct?

Jo, you have that right I think. If he is far enough away, then he can't claim the job block for himself.
