New beta build! https://wiki.arcengames.com/index.php?title=AI_War_2:Multiplayer_Alpha_And_Beta#Beta_2.751_Repairs_And_Clarity
You need to use the current_beta branch on Steam or GOG to play this one. If you have trouble with it, there is a most_recent_stable_beta, now, too.
This one fixes up the way that repairs work after ships are crippled so that it is no longer the old exploity way, nor is it the new annoyingly-slow way. If you didn't know what the old exploity way was, then that was the old annoyingly-slow way also. Either way, now there's an economic impact from having a transport cripple, but not a slowdown in gameplay. That's a big win for everyone, since it keeps things moving without confusing new players or making anyone wait wall-clock time.
Guardian balance has been adjusted a lot (them in waves at mark 3 baseline was intense, whoops), and some various mapgen fixes are in (insufficient bastion worlds are no longer, etc).
There are still a few known issues from recent stuff, including that the AIP from warp gates is still given to you if you did the hack to try to avoid that. Didn't quite have time for that one today. Also in this build the AMU mod and thus also Kaizer's Marauders no longer work, because we made some changes to the base game features (repair) in a way that it let you override. Hopefully that mod will be updated tomorrow or so, but I can't speak for the mod author.
All in all, this is meant to be a polish release, where the focus is making things less annoying or less confusing, in the few places where those traits were present. Enjoy!
