When I played D:OS I did not encounter any obvious bugs ( though some things seemed to be strange, but I was not sure if it was intended)
Others did though.
Just don't mistake your personal experience with how think were on a broader level.
You got a point there.
When you look at the forums, you see many people reporting bugs. And you thing that the game is completely buggy and unplayable.
But people who do NOT have problems with bugs do not report that they have no bugs. Because of this we will never know the ratio between people who have problems and those who have not. All we have the the minimum number of people who have problems (I mean, everybody who posts has a problem, but not everybody who has a problem reports it in the forum.)
