This one adds the expansion's 3 non-brutal core guard post types. An AI Homeworld gets about 8 core posts in general, and picks a few (from 0 to 3, depending on difficulty and sometimes a little randomness) from the "brutal" list like Core Raid Engine and Core Wrath Lance, and the rest from this entirely innocent, very non-threatening list of core guard posts. Minor sarcasm may have been utilized in the last sentence.
There's also some rebalancing of the expansion's "Lightning Torpedo Frigate" bonus ship type, since that was causing some excessive grief in AI hands. Let us know if this is better, etc, please.
I'm also very glad to report that I think we've finally crushed the last "AI cloaked threat hanging out indefinitely on human planets without doing anything" bug. Basically it was down to just the Zombie ships now, and that's been dealt with. If you see it again, please let me know and please include a save file where I can see it myself.
This is a standard update that you can download through the in-game updater itself, if you already have 4.000 or later. When you launch the game, you'll see the notice of the update having been found if you're connected to the Internet at the time. If you don't have 4.000 or later, you can download that here.
