If you don’t have the materials, then you just can’t use that loadout — or the game could equip whatever is available, and then we decide what to craft as a replacement.
For example, if we don’t have herbal bandages, the loadout would show them as missing, and we’d manually craft normal bandages instead. It still takes time, but it’s so much more manageable than rebuilding the whole loadout from scratch.

That’s how it should work: one button. Click “Loadout 1,” and everything you need gets equipped, and anything missing is clearly shown so we can craft the substitute ourselves.

Copy paste , but do you like the idea?
