1: If you set up the NPCs to look a certain direction and you leave the area and come back, all the NPCs are looking to the south and not holding the direction you faced them in with the /npc look command. And yes I turned off look before leaving the area.
2: Due to player collision being a thing on 1.9+ players are able to push the NPCs around. I have this temporarily fixed by placing barrier blocks on the back and sides of each NPC.
Any work arounds for these two issues?
