Hello.
There is an issue with the SM79's torpedo sight. It's not caused by the last patch, but I hope it might be fixed in a next patch.
When the "toggle sight view" is selected, the player's point of view doesn't follow the slip of the torpedo sight, like it does with the similar device of the B5N2.
While it's easy to release a torpedo with deflection against a moving ship from a secure distance in a 'Kate', with good accuracy, it is not possible to do it so in a SM79.
Thanks.
