After finishing the main quest i took my recently acquired ancient falmer armor and vampire royal armor to my house in the Pale (hearthfire plugin). I placed the itens in the mannequins and went off to do some other quests. After a couple of in-game days, when i returned, the mannequins were empty. I tried reoloading to earlier saves, but had no success. Then i though "well, guess i'll have to cheat to get them back", but when i try to add them to my inventory via player.additem, it says "compiled script not saved" (or something). Is it because of the "xx" in the item IDs (ex: xx00c815) ?
