I've already mentioned it in a post in the Sherman Hill discussion thread, but I guess it doesn't hurt putting it over here as well. Long story short, the reefer cars on the Sherman Hill route have openable doors, yet they show no cargo inside, even when the car is set to loaded. As can be seen in the screenshots below, the consist description says [Loaded], yet the cars in the simulation are showing up empty. Now it's not a huge thing, but when all other freight cars on the route (container, coal and autorack) show their loaded freight, why not this one?
That's very strange. In the files there is a cargo type made specifically for the reefer which is invisible but adds weight and locks the door permanently (same for boxcar). In modding testing that system works fine. Not sure why DTG didn't set that up for the playable loaded formations.
