Since the patch yesterday almost every other game I have participated in has had server disconnects. I can tell you it seems directly related to the patch to me as I was not getting them before. I am not the only one that seems to be having this problem also. I work with two other guys who play this and they are also having the same problem.
I can confirm this one. Getting a "Lost Server Connection" on mostly every game, since 1800 GMT. Playing AI games, happens roughly around minute 20. So no really big armies, played games with more unites ealier that day. Something not stable with your servers?
I'll investigate server logs. Might be a server crash. Haven't seen any appearing with regularity of late, but they can sneak in despite our best efforts.
Played 3 long games (30+min) on EU servers today and experienced no crash so far. So maybe that was a temporary server issue? Will keep you posted if i experience another game crash.
