MC-9813"Pick Block" on certain items then switching to survival creates infinite or ghost items
If you use "Pick Block" on certain items (listed below) in the creative inventory to duplicate it, after switching to survival (via /gamemode s), all except the last cloned item either turns into an "infinite item" or a ghost item when you start using them.
Steps to reproduce:
- In creative mode, put an item to the first slot of the hotbar.
- Use "Pick Block" on the item to obtain a duplicate.
- Put the duplicated item to the next slot.
- (Optional) Repeat steps 2 and 3 a few times.
- Switch to survival mode /gamemode s.
- Start placing or using the item and now you either have an infinite item, or it simply disappear and do nothing.
Behaviour of infinite item:
- You can place the block/Minecart infinite number of times.
- When dropped and attempted to be picked up in survival, it fills up your inventory infinitely.
- When dropped and attempted to be picked up in creative, it turns into a ghost item.
- When put into a dispenser/dropper, it can be dispensed/dropped infinite number of times without being used up.
Items that will turn into infinite item (incomplete):
- All types of Minecarts
- Doors
- Splash potions
Items that will turn into ghost item (incomplete):
- Boats
- Splash potions
Note: The bug with splash potions had been reported in MC-9361, but the behaviour is inconsistent, i.e. sometimes turns into infinite items while sometimes turns into ghost items.
