A few bugs I've noticed while playing this weekend:
Bugs:
A) I tend to build large clusters of turrets near wormholes, and am disappointed that turrets don't shoot at astro trains automatically. I assume this is because they have tons and tons of health, but if my cluster would shoot at the trains every time they went by, for the entire game, I could knock them many millions of HP with each pass, and by the end of the game (after a number of passes, and after installing a number of Mk. III turrets at my chokepoints toward the end of the game), I may actually kill a few trains. Right now I sometimes micro this, but I'm afraid I'll never actually destroy any if it doesn't happen every time (i.e. automatically).
B) Custom star layouts (I forget the official name, but I'm talking about when I shift-click-drag stars around on the map you see by hitting "tab") work great, except that when I reload a save, it should remember if I was viewing my customized view and not the default view. I prefer to always use my custom view, and right now I have to manually go choose to view it each time I load a save.
C) Transports seem to load much slower than before. It used to be, if my transport was stationary, I could unload all 200 ships in a transport, let the ships' auto-fire take out a few targets, and then load the transport back up almost instantly. Now the transport seems to need to linger for a while, for all the ships to load back up. It seems when this happens, a number of ships are right there on top of the middle of the transport, they just don't go in for a few seconds, like they're all at the right spot, but only a few can go in at a time. Was this an intentional change, or is it a bug?
Other comments:
1) I love the new command stations, the mineral harvester upgrades, and heavy beam cannons (even though these have been in a while)! These all rock!
2) I've embarrassed to say I've never beat a game of AI War yet, as I usually lazily try to conquer too many systems at the beginning without enough defense, but I'm actually being careful this time, and am playing a game now which looks like it could become a success. I'm looking forward to trying the new revamped endgame.
