New build! https://wiki.arcengames.com/index.php?title=AI_War_2:Multiplayer_Alpha_And_Beta#Version_2.708_Mapgen_For_Multiplayer
The last of the known lockups with multiplayer clients is now fixed, plus a variety of less-common MP bugs. Also fixed up the behavior of artillery golems and similar so that they will never chase units. Some bugs that led to super-speed warden or CPA fleets are also smashed. And a kind of nutsy bug that sometimes made the hacking costs of the get-science hacks really high in the last few weeks.
Lastly, this also includes a huge number of overhauls of how map generation seeding happens for multiplayer when there are multiple human empires. This one of the bigger things that had been on the list for multi-faction multiplayer preventing it from reaching beta, so that's a great milestone. There are now finally enough fleets and such for everyone to have a good time. Expect the AIP to be vastly higher in multi-faction multiplayer in general, and there are fewer AIP reducers to go along with that; you're going to really need to use your combined forces, since you're all getting so many fleets and powerups now.
