Version: 4195-Spigot-fcd94e2-f057cf4 (MC: 1.20.6) (Implementing API version 1.20.6-R0.1-SNAPSHOT)
Guidelines Read: Yes

 Description   

〇Condition: Set the spigot.yml item "hopper-amount" to other than 1.

 

〇Example of prerequisites
・A combination of hopper and chest, each filled with one type of item.

・The same item exists in both the hopper and chest

 

〇 Phenomenon occurrence condition: Take only half of the item from the chest by right-clicking.

 

〇Phenomenon: When half of the items taken are sent to the chest, the number of items in the hopper does not decrease and remains the same.
As a result, the number of items obtained will multiply.

 

〇Expected result: If you get half of the items, the hopper will send you as many items as you got.

 

〇Note: A similar phenomenon was confirmed with the following versions.

CraftBukkit version 4267-Spigot-5bbef5a-403accd (MC: 1.21) (Implementing API version 1.21-R0.1-SNAPSHOT)
Does not occur with Spigot1.20.4

Please can you test 1.21 (#4271). Once you've confirmed I'll apply to 1.20.6 as well.

I set it to 64. Even if I set it to 63 or 2, the problem occurred.

I am having trouble reproducing on 1.21.

What amount did you set in spigot.yml?
