Dunno about others but I couldn't believe F5 doesn't work in this game.
I was utterly disappointed, how can it even be possible in year 2017?!
Finished the game without it anyway.
In case you believe autosaves are not frequent enough, apparently you can force autosave by switching favorite profiles (F keys).
Sometimes it seems like manual saving isnt possible but all i have to do is move the mouse pointer up and down some over the save buttom. Weird but sometimes it allows me to save at moments i thought its impossible. Not always though, sometimes the game is as bitchy as it seems to be :P
