You're not giving any sort of specifics to what these bugs are that make the scenarios unplayable. Nobody would be able to help you if they don't know what's wrong.
Which ones are broken and what happened? I need to double check but I am very positive that I completed all the scenarios including both dlc on Peninsula Corridor, in which case it might be fault by user. This is why we need to know what went wrong - so we can either help you out or relay possible bugs to DTG more vocally.
