mike_espo,
You should download the db editor and take a look at the mechanics of the game.
What you refer to as "bugs" are simply values in a datafile. The ohio is listed as being noisier than the average SSN, this is because all stock DB values are tended towards catagorical averages rather than RL values in a lot of cases because SCS can't compromise their information about some things.
Yes, we all can surmise that the Ohio class is one of the quietest subs in the world, but SCS coded it in the game as being a mid-late cold war SSBN, which tend to be noisier than modern SSNs, so there you have it, a loudish Ohio.
If you want a quiet Ohio, then you can change the values, a single number in this case, and change it.
A bug takes effort to fix.
