I was perfectly sober, you dolt!!
Seriously, we did see this in 2.0 and experienced it in 2.5 tonight playing the Gateway map with two Human (well, if Bfiguero is actually human, that remains to be seen)
and 4 AIs. The game desynched within 10 minutes. He sent me his log files and I forwarded them on along with my own to the Support e-mail address and was floored when the Support person WROTE BACK (no, not just the autoresponder, a real reply) at 8:33PM PST. - Very Impressed...
On a whim, I had saved the game immediately on start, and we tried to reload that save and it appears to have desynched at about the same tickpoint, but I didn't really look. I assume this isn't a latency thing (we're both on Comcast's backbone albeit on opposite ends of the Western US) so it's not a bandwidth issue.
Josie/Blair - if you need more logs, let me know (you have my e-mail address). I can always sucker him in for more punishment...
