I've noticed a rather large bug with the Planet/Ship List tool located in the very left of the main toolbar in the main game screen. Whenever I click the button to select a ship on the list and then command that ship to move, the game crashes. I'm not sure why exactly it does this, but it's some internal programming bug, no doubt about it. I haven't seen anything like this happen before in the game, but its been interrupting my games a number of times because of its subtle nature.
