The Bug:
Freezing the game with the /tick command and then tick sprinting during an item's pick-up animation creates a glitched item that is synced to the player's movement.
See the provided video for a better understanding:
[media]This bug was also reproducible on a multiplayer server with nearby players sharing the same visual experience.
Steps to Reproduce:
Drop any item onto the ground and wait so the item can be picked up again.
Run the following command to freeze the game:
/tick freeze
Once the game is frozen, pick up the item.
Position yourself a few blocks away from the drop point and run the following command:
/tick sprint 1t
(For a better visual, try running the command again).
Move around and observe the movement of the item.
Observed Behavior:
The game desyncs the position of an item if the game is frozen during the pick-up animation.
Expected Behavior:
The game does not desync the position of an item if the game is frozen during the pick-up animation.
