Hi all, I'm losing my mind here, I keep getting quality coal in my coal train without having any quality modules installed in my big mining drills. The train will get stuck like in the first image and I have to manually clear it to get it going again, then it runs fine for like 50 hours before it gets stuck like that again. If I blueprint the entire mining outpost you can see that there are no quality modules in the entire blueprint. Looking at the production graph it also shows that no quality coal has been produced in over 250 hours, yet it still keeps magically appearing in my train? At one point this outpost WAS used with some quality modules but I completely rebuild it, is there a phantom module or something stuck in one of the drills?
