FTB Infinity: Zombie like thing opening my doors

[bluebird282]

Twice now I've been in my home and heard the door open and shut and look at it to see a creature walk in. It looks almost like another player but I'm in single player mode and it attacks me. They both had names over their heads and one of them dropped two rotten flesh when I killed it.

What are they and how do I stop them from getting in?

Build better defences [iron/piston door, or a few mod items to attack nearby hostiles]

As phoenix said. Zombies on hard difficulty also break the doors but your problem is some kind of smart zombie.

Its the Head crumbs celebrity mobs either build strong stuff as someone said or disable the mod

You can always use the carpenter doors/pressure plates. If im not mistaken mobs should not be able to get trough
