In 2021, Millennium Dawn was heavily reliant on specific assets and map data. This crash was almost always caused by a desynchronization between the mod files and the game executable, usually triggered by an automatic Steam update.
When asking for help, include:
The Graphics Cache Clear:
HOI4 holds onto old map data like a hoarder. If you updated the mod but didn't clear the cache, the game tries to load 2021 assets over 2020 map data.
The 2021 Bug: A specific event chain related to "Russian Oligarchs" and "Yugoslav Succession" had a broken code reference that only fired on the first tick of the new year.
The Fix:
Players in 2021 reported that while the game started fine, it would inevitably crash around 2025–2030 in-game, or during large-scale wars in the Middle East or Asia.
If you have tried everything above and still crash, your PC's memory management is the culprit.
