(EXPETIONS!: Arrows, Enchanted book)
While i was happily building my house in creative mode, I found a bat inside my house, i killed it with a bow. Then when i wanted to pick a block (with my bow in hand) that wasn't in my hotbar it didn't pick up.
What i was expecting : The bow is changed to the block i picked
What happened : Nothing, the bow stood there, in my hotbar
How to reproduce : Have a bow in your hand. Fill 8 hotbar slots with block 1 (example) try to pick block 2, And it isn't picked
