You need to change the settings.
1. Go to File
2. Preferences...
3. Go to Test Map tab
4. Untick the Use Fixed Random Seed
The use of this option is to run experimenst/tests that need to be in a controlled/static state so that the user can re-run it as many times as they want.
Even if you produce the map and have the option ticked, it does not take into account that the option would only work in Test Map, but not via game (LAN Game or Single Game).
