Hearts of Iron IV

Paradox log adapter: database, mod-descriptor and playset errors correlated with session evidence. One error.log entry does not confirm a crash. Test Millennium Dawn in a separate playset.

Common problems and next checks

Crash przy ładowaniu moda / Mod loading crash

Match HOI4 to the author’s supported version and create a separate playset. Do not combine total conversions. Retest without submods in a new campaign.

Duplicate / database / descriptor

Check for duplicate local and Workshop copies. Preserve logs before restarting; check dependencies and the .mod descriptor.

Wysokie obciążenie przy starcie / Loading load spike

CPU/RAM load alone does not prove instability. Compare subsequent gameplay and process termination; use Session Truth when the verdict is uncertain.

These symptoms are hypotheses until confirmed by logs and a repeatable test. Preserve saves and change one variable at a time.

A selection of popular community mods, libraries and tools; not a current ranking or a tested compatibility pack. Some entries are historical/Classic and require a suitable game version. Follow the author’s current requirements, dependencies and DLC list. Do not install the whole list together.

Evidence and limitations — ONE 0.8

ONE 0.8 uses diagnostic rules 1.4. Log evidence is matched to the game executable and session time. Mod configuration warnings are not proof of a crash or of a specific mod being responsible. Unknown outcomes require player confirmation. Real-game validation is still in progress.
