Every time I restart Endless Space, the auto-scrapping, auto-upgrade, galaxy scale and "lock end of turn" options set themselves to off. Even when I set them on. So this leads to two questions

How do I fix this so I can set those settings to what I want ?

Other settings save correctly. This is on Steam, Windows 10, with the Disharmony DLC.

I've also been asking for help on the Steam forums, where I've got someone telling me that the 'lock end of turn' option doesn't do anything in single player, which means I won't care about it resetting. I'll leave galaxy scale off whenever I have a mouse wheel.

But that still leaves auto-upgrade and auto-scrapping that need fixing.
