Almost all of my switches are pointing to the wrong direction. If the little arrow shows left, the train goes right and visa versa. So I thought, ok, this is a bug. But some days ago I layed several new switches, and two of them are pointing to the correct direction. I can't figure out what's different with these two. But it don't seem to be just a bug. There must be some law behind it, which is still bugged, but I can't understand it anyway.
