So in my previous game (the one I for which I had begun to write up an AAR) I ended up having to stop playing and delete the game because NPRs began making my computer crawl. 45 minutes to over an hour for calculating an un-interrupted 5 day turn is just insane. Anyway, I started a new game ... and this time I made sure to disable all NPRs ... 0% NPR generation chance, no starting NPRs, all spoilers disabled ... the intention here is that I would be playing my own aliens. I've got a 3 faction start, each in their own system an unknown number of jumps away from the others.
And yet ... lo and behold ... one of my races has just run into three unknown wrecks. Now, unless I've missed something there should be no alien races whatsoever other than the ones that I myself am controlling. Are there super-top-secret spoiler races that are even hidden from your game generation? Or is something broken? If there are NPRs about, they seem to be being much nicer to my processing power than in my previous game ... but there shouldn't be any. Where did these wrecks come from?
I'll update this thread if I actually figure that out on my own, but the question stands.
