[XXi]

Well, certainly it is NOT a problem, but... sometimes I think the problem is there are some essential bugs or things that could be made better, though... mostly, they`re too complex or problematic. The infamous bug of XXI SNorkel radar for example. I wish it was solved, but despite of best efforts it hasn`t been made so far.

By the way, another thing I`m thinking of is some change to the U Boot damage model.
What annoys me is:
repair times
-almost no leaking or no leaking at all ( considering the place of fuel storage, the leaking should be somehow common damage )
-if your steering is jammed by the DC explosions, you cannot turn and move only STRAIGHT forward. Technically, you should move in the way forced by the position of jammed steering
-I`m not sure about the depth rudder; if their damage causes problems with changes of the depth and so on
-I suppose steering should be available for repair only when surfaced - I presume that it SHOULD be hard, to say the least, to repair external thingy from submerged U Boot.
-Hydrophone should be, as I presume, more fragile and more exposed to damaqe from DCs.

.... so much so far. Perhaps it IS some mod idea, to improve this issues ?
