How to change hull damage when sub lie on the bottom? (mega sober mod)

[BeszotPL]

Hello
I`m old men I` played Silent Service in 80th ... So please talk to me very slow...
I have 2 questions:
First
I use sober mega mod - with generic patcher. BUt when my sub lie on the bottom hull integrity slowly decrease. Slowly but still. I would like to disnegage this process. How? What file, what to change?
In my opinion - I love read books of Second World War, memories of many sub captains, sailors (Germans too) lie on the bottom can`t damage sub hull. So I would like lie on the bottom without any damage at any time.


Second
After some patrols ,many time i open and closed recognition/ID book (with German eagle and swastik, its SOAN mod? I`m not sure) And suddenly this book disappeared! I think, that book is closed and moved out of the screen - is invisible.
How can I make her visible? Open on the center of the screen?
Other charts are visible - minefileds, shipping, manouvering charts and many others.

Please help me and write cleraly, please, i`m not so good in mods, files, py files...
