The Railyard is getting ridiculous

I'm having the same experience as jordomac this week. Nothing but metal for all three railyard tasks, all day yesterday and all day so far today. Fortunately I have Brandine and Jesse, so I'm able to keep the pair of them with Hippie Guy and Burns on metal, but it looks like this might be the first week ever that I don't manage the 5 donuts. Getting so many bonus donuts from the casino that it doesn't seem worth taking characters off casino tasks to make metal.
