Iron golems are becoming aggressive and not reverting to normal no matter if chunks are unloaded, golem kills you, trade with villagers, restart minecraft, or restart the entire console.
Has been an issue since 1.11 but none of you wanted to acknowledge the report I made TWO MONTHS AGO so here is another one.
Please do not duplicate your own reports. Instead, continue to update MCPE-46073 with new information and affected versions as you come across them.
