When you summon an item with the summon command, you are not able to pick up that item. Even when you use the PickupDelay tag, it doesn't works.
What I expected to happen was...:
I summoned an item, and I could pick it up.
What actually happened was...:
The item gets summoned, but I can't pick it up.
Steps to Reproduce:
1. Type in this command:"/summon Item ~ ~ ~ {PickupDelay:3}
2. You summoned an item. Try to pick it up.
3. You are not able to pick it up. (you can only kill it with a kill command, stand next to that item and type:"/kill @e[type=Item,r=3]")
I think you have to use
{Count:1}else it creates a item with the count of 0 so you cannot pick it up
