when clicking on a new campaign mission that was added to the shell either in a new campaign or an existing one the launch button does nothing. if i append them trough the addon they open and instantly crash. safe to say that campaigns clearly dont work on the new version of the game thanks gog and steam for messing up this great game.
GOG has a shell file of its own -- feel free to revert it with its patch, and enjoy the game the way it was with your custom modifications :cheers:
