When iron golems actively attempt to move away from the village to attack mobs, they will move slowly, attack less frequently, and refuse to look directly at the enemy when far enough away from the village. This could especially be a problem when the iron golem is attacking mobs like skeletons, ravagers, pillagers, and evokers to protect the village.

To reproduce, try to lure an iron golem out of a village using endermites or other small hostile mobs. When the golem is far enough away from the village, it will move slowly and refuse to stare at the mob.
