Once again I searched but did not find a thread fitting to my request, so here we go:
Playing the kickstarter edition i noted that i'd never get an autosave before an ground-mission, so it seems the autosave feature is missing or bugged, really don't know. Additionally something like an quick-save button would be helpful. Maybe with an restriction that quick-saves in ground-battle are only usable after a restart of the game or something like that.
Before a start a new ground mission i get an _newFameSave_ file created in the save-game folder,
