When I was shooting at bells with a bow and arrow, I noticed that the arrows will bounce off the bell and clip through blocks. (located in the image below)
Updated description by @unknown:
Steps to reproduce:
Place a bell
Obtain a trident or bow
Throw the trident/ shoot an arrow at the bell
Observed results: Arrows and tridents are teleported more than 3 blocks north or east when hitting a bell from any side.
Expected results: Arrows and tridents bounce off of the bell at the correct speed and direction.
also affects items (kinda) throw an item at a bell, and the item will get launched pretty far away. other projectiles like arrows etc seems to teleport about 10 blocks away.
