I have a MIN set up to load Brick Clay and Sand with Grave. No other products. The MIN is set up correctly. I have four hoppers for the clay and four hoppers for the Sand with Gravel. At the tail end of the consist I have three Woodchip Cars that I plan on loading at a lumber Mill farther down the line. The stupid Woodchip cars keep filling with the Brick Clay. They are set up to fill with Woodchips. No other products. In the config file there are two kuids which I think are essential: -3:10040=bulk load and -3:10002=woodchip product. Any suggestions as to why the woodchip cars are filling with the clay brick? Thanks.
