We reverted the patch back to 1.30.4 due to technical issues.
//EDIT//
The release of the recent Europa Universalis IV update has clearly been a mistake and has damaged a lot of the faith many of you have. We did not expect that this update would corrupt ironman games or significantly affect multiplayer, and clearly it should have gone through much more testing.
We are reverting the Nakama update, so that going forward people will be playing with the version of Europa Universalis IV that was live before this update, 1.30.4.
We cannot, of course, roll back your saved games if you have already had them corrupted by this update. No reversion can undo problems that have already occurred, but can prevent more people from encountering them.
Before we return to the Nakama update, we intend more extensive testing to better identify any additional problems, and will explore the feasibility of a public beta. We apologize for ruining the Europa Universalis IV experience that so many of you have been having.
