Regarding the reports of ship health, I cannot reproduce the problem. My ship has infinite health and one hit kill for enemy ship work as well:
It may be that you have been unable to reproduce this particular issue, but I see other people have since posted having this problem and I have encountered it as well.
I have tried quitting to windows and restarting the game then both loading an existing save and starting a new game, but I still cannot get this option to work.
The only thing I have not tried yet is reinstall the game, though that is my next step.
However it will take some time due to download speeds.
If there is any other information that could help let me know and I'll provide what I can.
