Issue: Zombies ignore steve (lucky right?)
When walking at night, spiders creepers and skellys all are hostile at first sight of steve (can't say for enderman, they were not around at this time.) However zombies will look at Steve and ignore him until provoked.
Solution: none found.
Workaround: hit them and they become hostile.
