If anybody solve problem with laying mines, I think that other "problem" will be results of that action.
It means that we will be unable to see result of our mine field. It is historical correct, but we all wish to know if we sunk any ships.
Also, problem is in SH3 stock. We can lay mines, and if we be etc. 100 km away from field and some ship sunk on our mines, we will not get any information in the game.
