What I expected to happen was I would see the arrow fall down through the water and i would see it hit the bottom.
What actually happened was...:It became invisible from swimming in the water floating on top, and some angles outside the water,
I also noticed that I could see the arrows at CURSOR LEVEL 45 Degrees verticaly, but if i put the cursor lower, they disappered.
Steps to Reproduce:
1. Create a 3x3 hole 4 blocks deep
2. Shoot arrow in to hit the bottom
3.Invisible arrow from standpoint
