Made a map.scenario in world builder, how do I get it to play in the game?
Go to Mod -> Single Player -> Setup Game -> Map (Choose your custom map and tick on the load scenario if you also custom or start position)
I think I found the solution...What I did was to remove the game and re-install again.
Without playing any game first, I tried to load a Mod game and there is Save and Load Game option.
But I have not tested playing it...but since the option is available I think it should be fine unless proven...
finally I can play my game...
