As I get no reply on bug report then I add it here too. Coal for Koeblitz Energy is wrong. It says after you have fueled the loco that you shall couple from your back on the wagons but shifts is leading the front of the loco to the wagons and I can't change the shifts so I can go around the wagons to couple to your back of the loco as the instruction says. I tried to couple to the front but it is not changing to the next number(3) so I need to get around the wagons. Somebody else have the same problem? Any solution?
