The Helm was deliberately left off because it's available through the Heritage tokens, and we gave out a TON of those.
Jeremy, can you please search for an answer as to why the bugged immovable statues, stretched hides, paintings, and various other items which were obtained through an illegal means which is no longer possible still remain to haunt the world of Ultima Online?
Since these items were bugged, they should preferably vanish, or at the very least be added to the list of items which decay if not locked down or secured in a house/bankbox.
These items DO affect house placement, and block it, therefore they should be removed from wherever they remain.
The same applies to the dirt patches left over from the Solen Ant introduction, I recently found that there was a dirt patch where a house once stood which blocked house placement.
Your team was doing so well on making house placement blocking with waterbarrels ineffective, I see no reason why you shouldn't follow through with your efforts to improve house placement and remove bugs related to it.
Cheers ...
