Here's the link to the question of the game breaking glitch, and before you say it's not, there are other players experiencing the same thing.
Check it out and you will see what I'm talking about.
I never said that you didn't experienced this glitch. I said that there is no general game braking glitch in ME3, and that remains true.
This thread you linked was not in the Mass Effect board and so I did not noticed it. But the facts still remain.
The game files will be the same after a disc installation, so if the problem is not solved by a fresh installation you will still experience it regardless of the installation method.
It is your decision how to proceed.
If you got the game installed and run into the same bug feel free to open a new thread, but make sure that you open it in the Mass Effect section.
