Well, the AIs still do some work with long range raycasts, it's natural that that causes jittering so some extent. I really don't think anything can be done about it until we can make the grid structures easier to raycast in (read: fragment less).
About the disconnections/timeouts: sorry if something important here flew under our radar. I've never seen it myself, which usually is the best thing to get me to work
Send a recording of you timing out, best on my server (which, of course, sucks if no tournament is going on, I'll see if I can make it non-sucky one of these days, the provider upgraded the CPU cycles allotted).
Aaanyway, apparently, nothing got destroyed since rc4, and since the disconnection issues have been around for a bit, they can certainly wait a month or two. We have a release! 0.2.8.3 is live on Launchpad
. I'm a tad too tired to write an announcement on SourceForge right now, if someone else wants to do it, go ahead.
