On my save in 0.1.5, actually a few hours before the latest version update, I had a fairly big game issue. During one of the meteor showers I got into my coolant was smashed, and I had only seen the coolant once before on a derelict ship and never again. Turns out at 60% coolant, practically anything will take you from mid yellow to red. I'd like to suggest making sure that coolant is a much more common addition in shop menus ideally. When I upgraded my ship I did get a coolant refill, but having the option to buy it commonly if needed would be helpful. Enjoying the game.
