Yesterday the team at Paradox Tinto, the new internal studio at Paradox Interactive that's taking charge of EUIV's development, released a new patch for the strategy game that was attempting to update the multiplayer technology to make it easier to manage going forward.
The desire was to allow the developers to focus more on new features and content, rather than having to maintain the historically inconsistent multiplayer framework. You can read the official patch notes to get an idea as to what was supposed to have been changed. However, barely a day after the 1.30.5 'Nakama' patch was released, it's now been recalled. It seems not only did the patch end up making multiplayer worse, it is also corrupting ironman saves, among other things.
A post in the EUIV section of the official Paradox forums confirms that the historical grand strategy game has been rolled back to it's previous version - 1.30.4 - and the developers are working on fixes for the key issues as quickly as possible. While this will prevent more players from experiencing issues, there's nothing that can be done to preserve saves that have already been corrupted by the new patch.
