The multiplayer issue (and it is a huge issue!) can be temporarily averted for now by turning barbarians off, ruins off and turning city state slider down to 0.
Hosting a tiny game or a duel is playable to completion. Anything more than that and you are skating on thin ice.
I know it is less than ideal but as an avid MP myself, I hope it helps you at least be able to continue playing MP until a real solution is provided.
Unrelated; I know bashing Firaxis is the cool thing to do because they are the developer, but 2k is the publisher and they get the final say on what and when things come out the door.
Wow.
1. Turning off Barbs, Ruins and CS will not solve the problem. That was a rumour and I as well as others have repeatedly said so in this thread, that it doesn't change anything. Please in future read all the posts in important threads like this before propagating untruths and hearsay.
2. Playing with less people only makes resyncs and freezes less likely, it does not solve the problem. Please stop propagating hearsay. Some people cannot even play 1v1.
3. You know it's 'less than ideal' to not play MP? Dude... many of us only bought Civ 5 because we saw how awesome the MP was. The game now completely ruined in many people's eyes.
4. Bashing Firaxis is not the cool thing to do. No one wants to 'bash' Firaxis. We just want a working MP. Fixasis has had weeks to sort this out, but due to incompetence and/or laziness have not done so. We have every right to call them out of their stupidity.
Firaxis, they are lazy, incompetent, arrogant developers. END OF STORY. If you disagree with anything I said you are simply wrong and/or have some kind of bias (like employment/friends in Firaxis). This isn't bashing, it is simply stating the truth. They can't even make their own bug reports for something they royally messed up and have to rely on idiots like me to do it.
Firazis, I and many have sent you logs. You are incompetent and lazy to fix it. Reverse the update, not only was it rubbish but you ruined a game we all payed a lot for. I would demand you fix the update but its quite clear you are unable to do so, so just put it back to what it was before the update as that is infinitely better than not having a game.
