Can't buy and sell between my main and feeder cities. What happened?! Recent update mess things up?

Daniel is buying up all my good stuff. At first I thought I'd simply forgotten. Basically my fault.

Now I'm sitting here for a couple hours, brought both devices to move things around, and sure enough, my feeder city isn't selling anything. Despite I just placed about 10 crates of stuff, unadvertised, on the market.

Test before you waste the rare stuff to that evil opportunist Daniel.
