A20.6 B8 Changelog:

Due to Microsoft requirements, custom prefabs can no longer be saved directly to the game folder.
They will be saved to the User Defined Folder (UDF).
This default location is:
\AppData\Roaming\7DaysToDie\LocalPrefabs

To avoid having to re-save each POI one at a time in the prefab editor, all POI's currently located in...
\Steam\steamapps\common\7 Days To Die\Data\Prefabs
...should be manually moved to the UDF.

The UDF can be declared in the game launcher as a command line parameter.
Add the following to the command line:
Format:
-UserDataFolder=< YOUR_DRIVE_LOCATION>< YOUR_FOLDER_LOCATION>
Example:
-UserDataFolder=C:\MyUserData

The UDF can also be set in the serverconfig.xml file.
Format:
< property name="UserDataFolder" value="< YOUR_SERVER_DRIVE_LOCATION>" />< YOUR_SERVER_FOLDER_PATH>< YOUR_FOLDER_LOCATION>" />
Example:
< property name="UserDataFolder" value="C:\MyServer\Users\TFP\123456\MyDediSaves" />
