It appears as though the current devbranch stage is blocking the loading of saved games due to Bootcamp dependencies being saved into the saved game. As the Bootcamp modules are not present in the game, this causes a massive load of RPT error spam followed by a popup error message claiming:
"You cannot play/edit this mission; it is dependent on downloadable content that has been deleted.a3_missions_f_bootcamp,
a3_modules_f_bootcamp,
a3_modules_f_bootcamp_misc"
