The Missing Components menu is a window that appears after long pressing or clicks and holding a single item. This menu will display all the necessary resources needed to craft the item, showing what you do and/or do not have in order to craft the item.
Depending on the missing material, you may have the following options:
– Purchase any missing materials from the Trade House
– Quest for the missing material by visiting the Inn
– Craft the missing material if you have the resources
If it’s available, you can skip all of these individual steps by activating ‘Upgraded’ slots, which will appear as a button at the bottom of the Missing Components window.
