I tossed up 3 personal miners for S&Gs to see what was really going on with them. I used some Radioactive with PE of 997 roughly(don't remember whether it was that or a few less) added 1200 to each of them. Came back about 8hrs later and there is only 430 left in each. Now that is insane. What is going on here? At that rate I can't even mine enough radioactives to keep a couple running. I'll honestly stop making armor, leave the PE out of it, just make it back to 25/50/75 and I'll be happy, that way I can have resources and still have left over incase a shift takes me a day or so to find a good spot.
