If you took damage and save you'll see the breaking glass sequence after reloading to remind you of your damage.
That's no bug.
By default (Stock SH3) the HI indicator is visible at the crew screen showing your HI in percent any time. There are several different mods that hide this info. If you run SH3 Commander you should be able to check a box for toggling this feature on/off. You can't reset the hull damage in the middle of a patrol. You would have to dock in a friendly port or at a milk cow.
