* Zinc rareness FIX(?)
I created the issue and i will fix it. But still idk if this really helps. (It helped me)
At least it will make it more common in -32 and 2 Y distance. To compare its like in between iron and coal i belive.
* Update oregen.lua
Changed zinc parameters in first block block to match "lead noise" and "tin frequent". Please commit this! Zinc was a real problem to me untill i changed this file, now i can find about 10 zinc in 2 minutes!
