This is pretty tricky to explain, but projectiles such as arrows and tridents can get stuck in the air depending where you are going to shoot it.
When looking down and shooting a arrow/trident, it looks like it gets stuck into the shooter's body or something, i don't exactly know.
Reproducing the issue
- Pick a bow and a arrow or a trident
- Prepare to shoot with the item. make sure to be looking down
The projectile lands on the ground.
The projectile gets stuck in the air...?
This can be better seen in the video i attached.
