I only crashed a few times since beta, I don't know what crashes your client but it seems very very rare for me and I only experienced crashes on game exit so far so my guess is that the guy was attacked and combat logged, game crashed on exit
. crashes when in trouble are very convenient, FD should fix it by making ships stay online for a couple of minutes after logging off or not removing the ship when under attack or has just been interdicted, in those cases the ship doesn't disappear until the attack is over, best way to deal with combat loggers
