I looked in catalog_sp.ymt but anything with "DESC_" is surrounded by hashes, where are the descriptions stored in readable text form? 
Can I change them and How is that achieved?

 

Thx in advance

Hey mate!

I figured this out today. I'm not sure how to customize them, but I know how to remove them.

ITEM DESCRIPTION in your inventory wheel, eg. "Slightly Restores Health Core"...

<description>CONSUMABLE_WHISKEY_DESC</description> 
this whole line can be replaced with:
<description />

CATALOGUE BOOK Description in the shop catalog, eg. "Big Valley Apricots, the finest...."

           <item>
              <type>LABEL_TYPE_CATALOGUEDESC</type>
              <values>
                <item>CONSUMABLE_STRAWBERRIES_CAN_CATALOGUEDESC</item>
              </values>
            </item>

But im not sure if its as simple as remving it, I don't know how to edit it.
