Game crashes when loading save file from in-game/campaign

[bhavpatel]

Playing on Macbook Pro (2021 with M1 Max), have the monthly EU4 subscription, v1.37.1.0 Inca. Ever since the latest hotfix (post-Winds of Change), the game always crashes when trying to load a save file while in-game. Never an issue before.

• Reinstalled the game and verified file integrity via Steam.
• Issue persists across campaigns.
• Tried with and without mods (and I only use a font/UI mod) and doesn't matter if it's an autosave or a manual save.
• I have to force quit the application each time.

From the exception.txt file:

Application: EUIV
Version: EU4 v1.37.1.0 Inca

If instead you exit the the main game menu and load from there, is it okay?

If so you should do that, as otherwise the game memory space is not properly cleared. That's why when you exit a game back to the manu menu the game does a full restart.

Tested a couple times and the load from main menu seems to work fine. Though, I'm hoping to avoid the extra step if possible.

Is there a reason why the game memory space is no longer being properly cleared / can I ensure it is cleared? This issue of crash when loading while in-game is very recent, only since v1.37.1.0. Thanks.

That has been the case for several years; I don't know the details but my understanding is the underlying issue is very complex and the dev team felt their time was better spent elsewhere.

That said, why you've only seen this since the last patch I do not know!
