Issue description

Game version: v0.8.4b Update 4 / Build 593
Language: Simplified Chinese (zh-CN)
Platform: Windows / Steam
DLCs enabled:

  • COI-SupporterDlc v1.1.0
  • COI-TrainsDlc v1.0.0

Issue:
The game can load old saves normally, but creating a new game fails during terrain generation. I tried several different maps and random seeds, but the problem still happens.

Mods:
No mods installed. The log shows:
"Found 0 mods."

What happens:
When starting a new game, terrain generation begins, then the game either crashes/freezes or becomes extremely slow after an internal exception.

Relevant log errors:

  • TerrainManager: Generating terrain
  • Error during map generation. Trying again serially.
  • NullReferenceException: Object reference not set to an instance of an object
  • PolygonTerrainFeatureGenerator.GenerateChunkThreadSafe
  • FatalGameException: Failed to simulate erosion
  • IndexOutOfRangeException: Index was outside the bounds of the array.
  • ParticleErosionPostProcessor.simulateParticle
  • Deserializing null of type 'string'
  • Proto+ID.Deserialize

I have attached the log files. Loading existing saves works fine; only creating a new game is affected.

Please note that these crash files may not be directly related to the new game creation issue. When the new game creation fails, it does not seem to generate a crash file, and the timestamps do not match.

These crash files are likely from other crashes that happened while I was playing the game. However, I have attached all of them as requested, in case they are still helpful.
