I had a UI issue with the alchemy machine. It said it would create a scary skelly suit out of the skelly suit without accessories on it. Basically its a UI error with the machine. But for future issues, what if we added a weapon/armor selection system for the machine. This applies to things with UVs or even accessories. That way we physically selected from our own preset armors (if they meet requirements like level) and avoid a possible issue and so they don't have to look into the issue so heavily. By selecting specifically the item we wish to upgrade, we are sure of the one being upgraded and if we mess up it's on our head. It sort of is already but if you spam craft things and find one you wish to upgrade but doesn't and chooses another UV'd item, we can get quite frustrated.
Thoughts?
When you open a recipe to craft, go to your arsenal and open the tab the item you want to use to craft/upgrade is; in your case armor.
Click the one you want to craft.
Hover your cursor over that item on the materials list.
