Shop list template error

That was a long rabbit hole. At first I thought it was pretty simple. The icon and/or item page does not exist.

In [[Red Tail Jonathan]], where is the page [[Pure Energy Crystal Pouch]]? Since the page and respective icon doesn't exists, the [[Template:Item]]  produces the wiki code <nowiki>[[<missing Pure Energy Crystal Pouch icon.png> |20x20|link=Pure Energy Crystal Pouch]]</nowiki>, and renders what you see on all the pages. 

Example failure below

<pre>{{Item|Pure Energy Crystal Pouch}}</pre> results in

{{Item|Pure Energy Crystal Pouch}}

Then, looking at Queerchemist's examples, I noticed it has to do something with the #show query not rendering 'Pure Energy Crystal Pouch' compared to 'Swiftly Mobile Plate Shoulder', as shown on [[User:Queerchemist/Equipment]]. Why? No idea, but 'default=' does not seem to work the way we want it to. Nice table btw.

I think the best solution is to make wiki code to detect if a page does not exists, which I'm not familiar with, YET. This will allow us to skip the template code and just render red links.

In the mean time, I'm not sure where to start looking for broken items, but [[Special:WhatLinksHere/Template:Shop_list_row]] is a start.
