MissingMethod / Harmony
Check dependency versions and duplicate libraries in a test profile. Review author notices for retired or replaced mods.
Common problems and next checks
Symulacja nie startuje / Simulation cannot start
Preserve output_log and the save. Check assets required by the city; compare a new-city test with the existing save.
Pamięć / memory pressure
Check asset count and loading memory. Reduce the collection in a separate profile; retain assets required by the only copy of a city.
These symptoms are hypotheses until confirmed by logs and a repeatable test. Preserve saves and change one variable at a time.
