Due to losing some of their carriages and drivers, the delivery company which had the contract to deliver the rations have paid the Trade Guilds the money to end the contract.
The acts have also damaged the reputation trade route towards the city of Arkanglsk as many companies didn't wanted to risk it.
The ones who were gonna risk it would ask for ten times the money which would naturally be required as this caused a lot of problems for the trade union since they now either had to take care of it themselves or tell the Emperor.
But of course the first plan wouldn't work, the union had many companies coming together since majority would opt to not help.
Why? Because it needs money and majority were simply not willing to spend a dime for something they didn't care much about.
