The bug

Compasses that in containers still point to their directions from the player's POV even though they have not taken out from the container that holds them. They should have pointed to the directions right from the container. In other words, if the three positions (position where the player stand, position where the container holds compasses and the position where compasses are pointed to) forms a sharp angle, it can be found counterintuitively that the compasses in the container seems point to a wrong position.

How to reproduce:

1. Get 1 compasses, 1 lodestone and 1 container (chest for example).
2. Place the lodestone.
3. Place the chest near the lodestone but not too close.
4. Tie the compasses to the lodestone.
5. Put the compasses into the chest.
6. Stand close to the lodestone and think about the direction the in-the-chest compass point to.
7. open the chest and check if its direction is same as what you think.
