I have been working with the creation kit for a few months now, and have generally been able to figure out my own problems when they come up. This one, however, has me at a loss. I have added a couple of NPC's to the game in the past without problem. They are there in the game when I go in there, and they seem to function as they should. But in the last few weeks for some reason any new NPC's I have tried to make are not there when I go in the game. I have noticed that it started after I installed Dawnguard, although I do not know if that is the problem. When trying to place the created NPC's in the render window, I get the message "Textures: could not queue texture 0X247d78f." I do not know why newly-created NPC's do not appear in-game, but I do know that I understand how to create them, as I made several in the past and they are still there. But an attempt to use the new character's PRID in conjunction with the move.to player command indicates that it does not exist in the game at that time. If anyone knows why this might be happening, I would greatly appreciate hearing from you.
