Like water spilled on the ground, which cannot be recovered, so we must die. But God does not take away life; instead, he devises ways so that a banished person may not remain estranged from him. 2 Sam 14:14
Here is the scenario.
I have established a trade route between two cities. One city is full,the other has an opening. During the action where I activate the route I lay my claim to use the extra city bonus marker and place a trader to the right of the full city....(I want to gain the majority in the full city) do I ALSO get to place a trader into an open Kontor space in the other city during the activation of the trade route?
Just to be clear, you always place the "extra" kontor to the LEFT. The city does not need to be full, it just needs the first office to be occupied. It's generally not all that helpful gaining city control unless you are already tied for most kontors. It's primary function is to allow placement to expand or connect your network.
The extra kontor token can be powerful when you need it, but there are 5 of them, so they are more common. It allows you to do something that you can otherwise not do in the game, and that is place a kontor in a full city or in a city for which you would otherwise not have privileges. This can be critical to connect up a large network or take control of a hotly contested point-scoring city.
