I've just played this game which I didn't manage to record on video at the time but of which I did save the replay file. Played with blues via QM on today's next_version of beta 6.
A short video recording of the replay in which I try to point out the bug:
In short, time seemed to flow half as fast as it normally does and the building animation of buildings appeared glitchy from both player's perspectives too, as the moving model of a building wouldn't fully land immediately as it would appear that it should.
(yet another) edit:
I just played this game vs blues. (Besides being in slowmotion) I power surge blue's water pumps but only 1 of the pumps is affected even though they are adjacent.
http://youtu.be/XC85Mi8ZDUA the power surge is at 18:46
I've played with gameslayer and blues today and the games with gameslayer were normal speed and with blues were slow. I and gameslayer are in west europe, and blues is in the USA. The sample size is a little low, but I believe the cause of the bug may may be related to the distance between us.
