The summon command can't summon WitherSkulls/Fireballs. Even when i give them a directional tag.
I typed /summon WitherSkull ~ ~ ~ {direction:[]} and expected to see a witherskull flash and become invisible but still be there.
It said "Unable to summon object"
Steps to Reproduce:
1. Simple enough: /summon WitherSkull/Fireball ~ ~ ~
Environment
Put your operating system (Windows 7, Windows XP, OSX) and Java version if you know it here
