[Server Bug | Deed Duplication]
I have found that you can pick up doors again by pressing "E" (especially if they are not part of a building). I don't know if this is intentional.
If you have a deed placed in a box somewhere an pick up the door the deed stays in the box. So if you re-set the door you'll create two deeds. I don't know if both work, we haven't tested this yet, but we have in fact two deeds for one object.
Version: First alpha.
