This mod is great. It's fun to play, fits well with the vanilla game and is very stable. I actually haven't crashed once which is something I usually expect from a large sins mod. Though I haven't tried and huugge games and probably never will.
I'm not sure if I'm having a problem with pirates though. They seem a bit weak and confused most of the time. For funsies I decided to dump a bunch of credits (57k I think) so the AI would put a larger one on me and I could put some defenses to the test. But only a handful, 30 or so with a couple capital ships, would ever show up and theyd just kind of trickle in. Eventually after watching the still active pirate bases with scouts for a while I determined that raids had stopped spawning all together regardless of how much bounty there was.
I haven't played sins, modded or otherwise, in a while so I don't actually know if I broke something or if everything is working as intended.
Also I got the same result with and without the powerful pirates addon. And I should have tested the base game so I'll go do that too.
