Whoa that's abysmal. Was the whole mission aborted early? Are you sending enough frigates of the right kind on each mission?My worst haul yet for a frigate mission was the other day; 215 units and no resources.
I send frigates on all available missions each day that I am able, and maybe 1-2 frigates come back with any damage, if even that (out of at least 20 or so that I am sending out in total), they never abort the mission and come home early, and I almost always net at least a million units plus high-value resources which I immediately sell.
I have to imagine that we are doing something differently.
