During raids, ive noticed the fact that Iron Golems AI completly breaks apart,
there was a raid in my base so i naturally brought out the golems to attack the pillagers, Upon which i noticed that the iron golems were just Not fighting,
They either stand there and idle arroun as they are shot, or they spin in circles, or turn towards the illager attacking them and then back arround and repeat the process
they will attack if they are in range (sometimes) but they wont approach,
These were naturally spawned golems, snow golems seemed Okay,
Did you use a lead on these golems? There's an issue reported for what you described which seems to be caused by using a lead on the golems.
