Items disappear after crafting then closing and reopening inventory

Various items randomly disappear, especially straight after crafting.

I've had a Shulker Box full of my precious, precious maps just blink out of existence, several chests and pieces of paper also vanished after crafting and made me question reality.

 

I can't show a video as it happens randomly, and is not replicable.

Steps:
1. Prepare correct materials and open the crafting interface on the crafting table.
2. Select crafting recipe and craft via quick-craft shortcut.

Result: Item appears and  then disappears when I close and re-open my inventory. Items broken or dropped, such as shulkers and leashes, vanish also.
