I couldn’t find anything on this so I thought I’d bring it up.
In Crafting, when you Fracture an item, the game removes the Glyph choice. This can result in having an issue where the player will accidentally not choose the Glyph again when crafting the next item if they were planning on crafting multiple items at once.
Additionally, when you set an invalid base item (for example, a Unique), the game also cleans out the options you’ve chosen. This is quite a nuisance when mass shattering items, for example. If I’m cleaning out my inventory by shattering everything I had on me, and a few Unique/Set items are mixed in, the Rune of Shattering is deselected for no real reason because the player cannot even attempt to do any kind of crafting with a Unique.
My suggestion would be to keep the option but ignore it if it doesn’t apply for what you’re doing (maybe a red indicator on the UI element is in order as well). In both scenarios mentioned, the player cannot click the craft button even if they want to, so cleaning out the options they have chosen doesn’t really make sense.
