Without any speed and without manual dives planes?
guess i have to try again in single mission.
ÉDIT:
In PK17 mission, dived to 190m.
It seems impossible to maintain depth without speed, or the sub is slowly sinking.
Ahead slow is even not enough...
It sunk to 200m!
I had some difficulties to go back periscope depth (without blowing ballast)
But noticed strange things too.
Around 150m, my inside camera suddenly was side flipped like if the sub was leaning on a side.
But with outside camera the sub was not leaning.
I had this too once in my career, so it’s not new but very annoying.
Then around 180m 2 crew members were hurt! Don’t know why...
I took the hydro station, then exit, and camera was leaning the other side!
Had to wait surface, exit on deck, then back inside and camera was ok again.
