I'm interested in the answer to this too, although not the uploading part - the gremlins part.
I did a little bit of redecorating (in the CK) on the Riften Player house just for my own personal enjoyment of it. Everything looks perfect till I get in game, then the vanilla player house items I moved keep re-spawning in their original spots. I have clicked both "do not havoc settle," and un-clicked the respawn on the offending items, but they continue to respawn in their original xyz positions.
The statics I moved have stayed moved, it is only the havoc/potion and misc items that are continuing to spawn in their old positions.
I've been afraid to delete these items due to Skyrim's issues with deleting vanilla placed objects, but what do I do to make them stay in the new place I have moved them to? Someone on the internet suggested deleting the X they are attached to which would remove that script; but if I shouldn't delete a little cup or piece of salmon, then wouldn't deleting that script be worse?
Gaaaah, Skyrim is so frustrating! Help! (Please?)
