Summary:
minecraft:behavior.move_to_block doesnt work on dedicated server

Impact:
entities not following behaviors and acting differently on servers is bad. This directly impacts the jigarbov holiday map and results in entities being unable to despawn which will heavily impact server load and eventually destroy the game.

Repro Steps:

download the jigarbov holiday map from the marketplace

start the game and complete the tutorial.

once the game is started, speed it up to the highest speed

fly above the residential area high enough that citizens will spawn (at least 24 blocks away) and wait for them to spawn.

 

Observed Results:
over time, the amount of citizens will increase to ludicrous numbers because they do not complete the move_to_block in order to despawn at the end of the night. this will result in the game becoming unplayably laggy over a period of time.

 

Expected Results:
citizens should go home and despawn over time.

Screenshots/Videos attached: yes
