Was towards the end of a single player game, (version 1.09, small random map, pirates inactive), when I saw a few pirate ships appearing out of nowhere near the enemy planet and flying to it. There were no planets in the direction they came from.

I would post a few screenshots but I'm not very "Forum Savy" and don't know how.

Also, I thought the problem with the frigate wanting to jump back to the nearest friendly grav well was fixed in 1.09? I've noticed that is still happening.
