I have a friend who does game QA. A lot of the time issues this major are caught, documented, and then management decides the extra delay to solve it isn’t worth the effort because “it’s not going to impact enough people to matter”. Then, once a firestorm erupts due to public backlash, they try and blame it on QA.

My friend has gotten very good at ass-covering, and makes sure every issue ticket is very explicit, not only in terms of what the issue is, the cause, reproducibility, but also how likely the average user is to hit it just to avoid blame.
