I've been trying to create a quest mod for some time now. Currently I have four NPCs and a house made. One of them I have placed in The Frozen Hearth in Winterhold. He shows up and works fine. However, the dog and another charcter I've made, which I've placed in the house I created, do not show up in game. I have used the console to teleport to their locations, and have been placed where I set them, but they just aren't in the house or anywhere. Also, I know with the one, the CK keeps telling me "MODELS: Could not find model", though the previews work fine. Before placing this NPC in the new home, I had her placed in Riften, and she showed up fine, I believe despite this warning. Any ideas what the trouble might be?

Actually, turns out I forgot to navmesh.
