!Warning about updating your project!

Please backup your project before updating any assets. For minor updates and hotfixes, you can update HR2 without deleting the whole folder. Update and import the latest version to the existing HR2. All HR2 resources will be updated, if your own contents are connected to any prefab of HR2, they will be overridden.

Delete the HR2 folder, and import the latest version. Keep your own assets outside of this folder. If you are using your own settings and configurations, backup "Resources" folder in the folder and overwrite default folder after importing the latest version.
