Birding, which I admit its the first time I hear this word, has nothing to do with it. We had the same problem in a multi player game with a player that got disconnected and had to hotjoin, and he had the exact same issue. Then I decided to rehost and the same thing happened to me. On the other hand a single player ironman game, that I didnt "bird", is running along fine.Yes I do bird sometimes. But I can assure you that this time I just closed the game and went to the something. When I decided to play the game again it was like this, you can even see I didn't bird since the game is at 14 September which was when I saved the game.
So maybe the bird is the cause but at least it wasn't related with crashing the game by itself
At least make a bug report, THEN come to this forum to complain. Doing for latter without the former is as useful as farting out of the window to heat your house up, might make you feel good but is completely pointless.
Like I said the game was started on the current version. A game shouldn't break in its own versionUpdates always risk to break saves. If this was saved on another version, then yes, you risk that the save breaks. Though that usually happens with major updates.
When things get really fucked up on an ironman save, all you need to do is open the documents folder/paradox interactive/savegames and move the automatically generated backup save out of the folder before you quit the game. You minimize the game, move the save game out, , quit normally and move the save file back and start from the backup(and your save file will be called f.e Persia_backup_backup etc). Now if he actually crashed the game on purpose yeah that might be it. As said before my single player runs fine still.A disconnect is likely to cause exactly the same issues as an intentional crash of the game (commonly referred to as a bird in the EU4 community because "oh look, a bird passed, damn, what happened, did not notice, my game crashed right when I fell in a PU under France, unfortunate, I was distracted by the bird").
I'm not even playing ironman and the issue happens. Looking at the error.log it looks like something is causing missing closing curly bracesWhen things get really fucked up on an ironman save, all you need to do is open the documents folder/paradox interactive/savegames and move the automatically generated backup save out of the folder before you quit the game.
