Sometimes, sort of randomly I get a CTD when I try to look at ship details from a ship in a fleet. It does not happen every time and usually after I have played for a while, but it does happen quite often.
The main reason I press the ship detail button is also another bug which is that hit points and movement are no longer shown when a fleet or ship in a fleet is selected. I have no idea why this information eventually disappear, but reloading the game fix the issue.
This is with the latest 6.2 updated version... 0.97.5 or what it is called.
