Some spider/zombie spawner rooms do spawn in the caves, which is nice. However, loot chests contains a little nonsenses

• Remove vanilla copper ore or replace with TFC ore (vanilla ore can be processed in very late state, but the copper would be useful)
• Same for vanilla copper ingot - TFC copper would be better...

will have another update out before the weekend with this and other mc ingots that were overlooked replaced with TFC variants. thanks!

swapped as many things as i could think of in the 1.2 update, copper, iron, gold diamond, etc if you are still finding any please let me know :)
