But where does copper normally spawn? I'm mining at 12 where I normally would for vanilla because everything can be found at that height but it doesn't seem to be doing it.
And one more thing, when I use the smeltery, the metal inside only works once. Ex: I put in 3 coppers I had to cheat in and one aluminum and drain the aluminum brass out. It cools into a blank cast and there is more aluminum brass in the smeltery. I try draining again but this time the liquid just stays there rather than cool forcing me to break the casting table and the smeltery controller. Is there a fix for this?
