I'm looking for someone who can help me with my villager problem, but this is a huge problem you need to know villagers good to help Reward:5k
I believe that villagers will run out of trades after 7 or 8 of them, forcing you to "reset" them by trading a different item. However, I think you can get a trade that doesn't run out if you get it into the 5th trade slot. I'm assuming this is what's going on here, except that it stopped trading.
Maybe you should check out this video if you want to know anything about villager trading: You can also get to the video by this link: https://www.youtube.com/watch?v=h-amlopYzAA&list=PLOfxMC0BlfPKWoK03sjuP0H5Z-kepf5o5&index=14
That's why I said I need a pro villager trader, this villager unlike others never ends on emerald, you can trade with him for a very very long time But mine broke I know there is a way to reset him just I don't know how
