I am assuming you found this deed on a non-production shard. The reason they are decorative on those shards is because it would have been a balance issue. People played that shard before PBDs were handed out would have an unfair advantage over those people who started on those shards after PBDs. I think the reason they were made decorative (rather than just removed altogether) was because it was already in the code, and they couldn't remove them on specific shards, without causing them to be messed up on other (production) shards. My only source for this info is the lump of grey matter between my ears, so anyone feel free to correct anything I may have gotten wrong.
