I was just shift-clicking my inventory and accidentally placed tipped arrow on my off-hand slot with no other arrows in my inventory.
I tried shooting it with an infinity bow and it doesn't seem to work as the way it is suppose to.
The result I thought that will happen:
- Tipped arrow disappears from your off-hand as the bow (with infinity enchantment) shoots it.
- Tipped arrow stays in your off-hand and infinity bow shoots normal arrows instead.
- Grab a bow with infinity on it.
- Place a tipped arrow (single) on your off-hand.
Happens in realms as well.
Happens on Windows 10 as well: Bug video for Windows 10 verison
