There is a small problem with the recipe file for the helmets asking for a Matter Block, eg, the Handy Space Helmet and the Neat Welders Helmet. It lies in the object name in the recipe file, it's asking for a "matterblock" item, which is all well and good, this is the item it turns into when it's spewed out of the machine in the dungeon. The problem is that the collectable item with the name "Matter Block" links back to an item called "matteritem" - they have the same image, but they are NOT the same thing. Screenshot time!! This is the recipe file for the "t2helm1" in the recipes folder. It displays the item needed as "matterblock". This is fine, it links to something, and doesnt cause an error - it DOES in fact exist in the game. Now lets have an example second item - the monster plating (referred to as its filename "monsterplating" in the recipe). When I checked for the "matterblock" item in the files, it did return an existing file with that name. However "monsterplating" is not in this folder - when I checked, this is in the same folder as building materials (Starbound/assets/items/materials). This struck me as a little odd, so I simply searched for "matter" - I was shown both "matterblock" and "matteritem" in the search list. This is the folder with "matteritem" inside (Starbound/assets/items/generic/crafting) and there indeed is the "monsterplating" item below it. To test this out, I edited the recipe file. It works. The recipe is fixed Thanks for taking the time to read all of this!
