I just realized that if I used a command to summon an item frame with a certain direction, it will only be summoned on a block facing north. I have the command:
/summon ItemFrame 160 58 -599

{TileX:161,TileY:58,TileZ:-599,Direction:2,Item: {id:filled_map,Count:1,Damage:8}

,ItemRotation:0}
However this doesn't work. Pretty sure this is a bug. If not, what is the command? - Thanks, I really need the command
