MC-209286A different enchanted book trade is selected when clicking on an enchanted book offer despite not having enough emeralds
When selecting a trade without having enough materials, it will still show subsequent trades the player can afford. However, if you choose a trade that's further down the list without having enough materials, it will not show trades the player can afford (intended behaviour).
To reproduce
- Summon a villager with the following command:
/summon villager ~ ~1 ~ {VillagerData:{profession:librarian,level:2,type:plains},PersistenceRequired:1,Offers:{Recipes:[{buy:{id:book,count:1},buyB:{id:emerald,count:10},sell:{id:diamond_hoe,count:1},rewardExp:0b,maxUses:9999999},{buy:{id:book,count:1},buyB:{id:emerald,count:5},sell:{id:golden_hoe,count:1},rewardExp:0b,maxUses:9999999}]}}
- With 1 book and 5 emeralds in your inventory, select the first trade
-> It will show the item of the 2nd trade.
Alternatively, to do it in survival (The steps below was provided by Alex in this comment.)
- Find a villager who offers multiple trades:
- The first trade
(E.g: 36 Emeralds + 1 Book => 1 Enchanted Book) - One or more other trades with the same first item, but at a lower cost
(E.g.: 22 Emeralds + 1 Book => 1 Another Enchanted Book; 9 Emeralds => 1 Bookshelf)
- The first trade
- Don't have enough items in your inventory to successfully buy the 1st trade offer
- Select the first trade (it only occurs with the first trade)
Actual Behaviour
It will select the first trade for which you have enough items (E.g.: The 9 Emeralds => 1 Bookshelf if you don't have a book)
Expected Behaviour
It should not select any trade (The right side of the trade should stay empty)
