I had just finished reading the first few chapters of Matt Forbeck's "The Rise of The Arch-Illager" where the zombies attacked Archie's raiding party, so I went to the main minecraft game to see if undead mobs (other then the wither) attacked Illagers, so I spawned a bunch of Pillagers in a room and spawned zombies... nothing they were perfectly cool with each other. Is this Intentional?
