I just finished the contracts with Samuel, after that I "received" as a reward a theme?, is it Savanna???, I can find it in my rewards, but as I click on it, a beach umbrella appears and that's it. I cannot use it or whatever. Next to that, in the ending contract is mentioned, by Samuel this time, that I can manipulate all the buildings at his station, to raise the income, etc.... of my station. As a fact I cannot do nothing of this kind of things at Samuel's station??????
