So, update on darklatiz' assault:
He was indeed just probing to see if I was active. I declared war on him, but he got the memo and retreated. Rather, he rerouted. He is now flying his two fleets toward KipJaw. I am flying some fleets to Kip.
I also just completed long range sensors. Yeehaw. Colonies are coming a bit slowly, but such is life.
However, combat doesn't work exactly how I thought. My fleets that I sent to attack him completely missed, and he "overshot" my planet and accidentally killed a subspacer I had out alone on my flank headed on a piracy mission.
