Error message about duplicate prefab name during game loading
If autosave is enabled in the asset editor, and you open an existing asset to create a new one based on it, autosave can save the work-in-progress asset as an autosave file. When you load the next game you may get the error message:
An error occurred
Duplicate prefab name [BrokenAssetException]
Delete the AutoSave.crp file from the “C:\Users\YOUR_USER_NAME\AppData\Local\Colossal Order\Cities_Skylines\Addons\Assets” directory.
