Yeah, the fact that the amount of Iron and Titanium elements are just bafflingly rare compared to other elements. I am hoping there are kind modders to kindly help this issue by making an actual reverse smelting process. Example is; player can smelt back Iron bars doors or fences from USMC Penitentiaries and turn in into usable Iron Ingots. Same with Titanium blocks and furnitures from Miniknog Labs into usable Titanium Ingots. This way, player can actually raid any dungeon not only for looting treasures, but also resources procurement. And I am sure, creative modders can expand the Idea to other furnitures and blocks, if it is logical to do so.
