Naturally generated iron golems are becoming aggressive and not returning to normal even after leaving the chunks and/or quitting the game and loading back in. I do not have negative standing in the villages where it occurs, and am only being chased because of accidental damage to villagers or golems. 

Steps to reproduce:

-Enter any village that has an iron golem

-Hit either the golem or a villager 

-Leave chunks and return

(IF GOLEM IS STILL AGGRESSIVE)

-Save & Quit

-Load game
