We established in bestiary more liberal pricing for placing lots. It was made for reducing the commissions and giving more freedom in pricing for players. 
Now you can sell resources in one-and-a-half times more expensive or cheaper without increasing the commission and the fleet in twice as much. 

The old rates were 1.25 and 1.5. 

For example, now you can earn on a construction of a rare fleet by selling it twice as much than construction costs without paying an increased commission.
