* You must polish the glowing hot metal object with a bundle of fur!
* You must sharpen the metal ball!
* Needing a [[mallet]] to finish or improve a mallet.* Needing a [[hammer]] to finish or improve a hammer.(Apparently hammering the surface or sides of a hammer back flat to repair or improve it is not logical? This one really doesn't belong in this list, nor does the mallet one above it)
* Needing [[water]] to finish/improve a [[clay]] item but not having a liquid container to hold it in (despite being right next to a pond/lake ''filled'' with water that the clay item can't simply be dipped into or water picked up by activating a hand on it).
* (No longer possible.) Attaching an [[anchor]] to a [[mooring rope]] and, if failing, the anchor becomes [[lead scrap]]. ''Only'' the rope should be lost (or just [[damage]]d, even more logically).
* [[Pile of dirt|Dirt]] taking damage and "crumbling to dust". Dirt doesn't [[decay]]...ever! If anything, when dirt is in a [[Pile of items|pile]], it should go back into the closest tile corner instead of magically disappearing out of existence. The universe doesn't work like that... And when dirt is in a [[container]] it should stay there forever.(Note: Soil, which dirt often represents in Wurm, does decay
* (No longer possible) Fitting large [[unfinished]] items in a [[pottery flask|flask]] or any other [[container]] that is too small to hold the item. Likewise, unfinished items weighing far more than their finished counterparts.
* (No longer possible) Building [[ship]]s in a [[cart]].
