New AI War 2 build! https://wiki.arcengames.com/index.php?title=AI_War_2:Post_Completion_Part_II#5.605_Multiplayer_Optimization
This one has some notably new options for multiplayer, to allow clients that are over-saturated with data to basically do less diff-checking in the background and thus reduce the incoming traffic.
This mostly applies to really heavy games with a ton going on in them, but Badger was able to get notable improvements (like 50% reduction in network traffic) with some of the options -- and then other times there was not really any improvement at all. So the options are there, with clients being able to try them out if they run into issues on a specific campaign, and we'll see how that helps.
There are also many updates to the Sidekicks mod, and a couple of minor bugfixes.
Enjoy!
