Glad to see you back Aplos! I'm glad to be of help distributing this mod! In case you're trying to keep track, the Megaupload file has has been dl'ed 237 times so far.
You'll also be glad to know I haven't found any major gameplay bugs either in ~25 hrs spent so far. I don't know for others, but the game has also been very stable for me.
I am on a high end gaming rig though (i5-750 @3.8ghz and xfire 5850's). At the least, this probably means no programming glitches causing minidumps.
Yeah, I'm glad 
You may want to look at pirate stats again though. Kyuuseishu does make a good point about them. Currently pirates ships do have a ridiculous amount of armor, and bases do require a lot more effort than makes sense to take out.
On the other hand, this is the first mod where I actually have to make sure pirates don't go after me mid game since if they do show up usually means gotta stop my attack and pull them back. Even with starbases the pirates can take out a planet without rest of your fleet to help out.
Well, mod doesn't has any adjustments of pirates, besides of their base (in 2.1 instead of frigates, they'll use appropriate droids, much weaker then frigates), as concerning raid capacity, it's the same as diplomacy 1.0 version (in Stars 2.1 it'll be insignificantly lesser). In my practice, basically pirates made appreciable damage to star base, but couldn,t destroy it, sometimes they also could kill the majority of planet population. Thus I'm trying to find such value of pirate raids, that were irritating, but couldn't totaly break defence, so player should always monitor raid inclination, and in multiplayer games it becomes primary investment of credit surplus
for some period... i don't want to loose such fun.
