Either it's a bug and that contract wasn't supposed to be in there at all, or maybe you can use the tour ride as a transport ride as well? Never tried it myself but we can use several stations for those now, right? So maybe that works. Or more and wider paths maybe. Also: is there even a transport rating in JP era now? I know it wasn't there in the first game.
Okay, sounds more like a case of this contract shouldn’t even come up in this era than anything else then. And to renew a contract go to the Missions screen in the control center. In the lower left corner there is a button to cancle the current contract and get offered a new one.I don't know. I had made paths wider and it had no effect. I think it might be a bug. I keep getting messages saying contracts have been refreshed but I can't choose any new ones.
