[Bugfix] GB Campaign

[609_Huetz]

I think the mission failures are intended as a hardcoded obstacle for players that fail to achieve the main objective in the mission, just to preven them skipping single missions.

Right now, most of the missions don't seem to have any predefined main objective (except the first few), so I guess the devs decided to just let you pass through no matter what the result in your previous mission was.

I am still hopeing that there will be a rank and award system introduced for future campaigns, just along with certain mission builder defined objectives to create more immersive campaigns other than just putting a few missions together and call it campaign.
