Funny as in I laughed out loud while dying inside..
Got a station defense mission and at my combat rank M7 spawn regularly which is what I use to train my marines in fighting. Recently my first to-be-elites batch finished their college degrees and we're ready to rank up their fighting skills to 100 (so each of them was 50+/95+/95+/95+). So i load up my Carrack and order it to wait at the station with the mission while I finish other business. Carrack jumps in simultaneously with a Q and its escort. Luckily emergency jump kicks in and it gets out with barely a scratch @96% hull. So send for repair.. mission timed out so I went on with business..
.. 2 hours later (in sponge-bob-narrator voice) .. piloting the Carrack myself.. juicy astreus with shields down in crosshair.. hit turbobooster for a fly-by marine droppod launch.. shift+c, 5, .. can't board??????..
Turns out, that barely-scratched-encounter
had destroyed the Cargobay life support (and only that).. with it my 20 best marines worth 40M in credits alone.. don't even mention the time investment..
