I set a diagonal set of mine tracks and the cart kept turning around. I removed the diagonal tracks and went to a simple corner and the cart worked. At the next corner the mine cart turns around. I attempted to break and reset the track in by laying it in different orientations and problem persisted. I placed a switch and when turned on the cart would turn one direction, but would be returned when trying to to the other way. This problem should be easily reproducible.
