Oh snap. I didn't know that. Haha I was reading this guide that was like "save all the malachite, collect malachite, malachite is uber rare" and I was like wtf I have tons of it and my runners can get it.
I didn't realize there's a malachite gem AND a malachite ore. FML.
hehe exactly the same happened to me. But I found out the hard way, when I was trying to do another enchant like I had done several before and it said I lacked malachite. And I saw I had a lot on my inventory. After some research on past savegames I noticed the malachite gems, but in my current game I had already wasted them :P
Well, not that the game is too hard without uber enchants ^^
