It's difficult to draw a line between "issues" and "things that could be enhanced". Some people started "fixing things" and ended up with a 1.5GB supermod
anyway, in sensors.dat, sim, etc, for german boats :
-wrong axis of rotation for german KDB hydrophone (model needs to be turned 90° in a 3D studio and reimported)
-hydrophones can "hear" ships when your submarine is surfaced
-"biskaya kreuz" shouldn't be visible underwater, same for the UZO
I'll edit if I think of more :hmm:
