Through rigorous and extensive testing of this bug, I found that, under certain strenuous conditions—the kind that could lag MineCraft to the point of crashing/freezing indefinitely (i.e.: approx. 100 Villagers and Baby Villagers being chased by about 200+ item-wielding Zombies, Villager Zombies, and Baby Villager Zombies, being in turn chased by 6-8 Iron Golems, all under the influence of Extended Speed I and II, Extended Strength I and II, Extended Regeneration I, Extended Slowness I, and other similar potion effects)—the Iron Golem bug could still occur. (Unfortunately, I couldn't reproduce the bug in that same method a second time for the purpose of taking a screenshot of it.)
