Playing the campaign, and while it is mostly enjoyable, I cannot be the only one to have noticed that the AI's torpedo boats seem damn near impossible to sink at times?
There have been scenarios where my ships have done over 4k damage to this dinky little boat, hit it with 3 torpedoes, and the AI still magically pumps out the majority of the water... You can get them down to 0.1% float-ability, and seconds later the ship be back up to 70%; when in reality this boat should be matchwood...
It really can be infuriating to watch, especially when the AI seems to build these a lot in the early years. Compare that to a battleship with the same level of compartments sinking from one torpedo, it just seems so bizarre...
