I do not have the crash readout as my friend is the one repeatedly crashing. When playing over LAN using hamachi, doing certain actions causes bugs.

Consistently repeatable:
When the player not hosting the world uses the spyglass, the spyglass effect also appears on the hosts screen.
When the player hosting the world uses the spyglass, the player NOT hosting will crash.
When the player hosting the world eats ANY food (including ones that give potion effects and ones that dont, passion fruit, sweet berries, bread, carrots), and the non hosting player is looking directly at them, the non hosting player crashes EVERY TIME.
The non hosting player attempting to turn the page in the animal dictionary resulted in a crash, however the hosting player doing the same did not.

Not easy to recreate:
Occasionally blocks will be invisible except for their outline, including blocks (an andesite stalagmite thingy) not placed by players, and blocks placed by players including torches, cobblestone, chalk markers.
