To make the game more realistic, this mod limits the number of different fill types that can be stored in a silo at the same time.
By using silo extensions, this number is increased.
In a silo, only a maximum of 4 different fill types can now be stored. By building additional silo extensions, the number of different fill types can be increased by 2 each.
Now also works in multiplayer!
