Okay! The only cause for my case was that in the config.cpp where it says this:
// ...longitude = -25;
latitude = 135;
startTime = "20:30"; //old time was 8:30
startDate = "03/25/2000"; ...//
Because of my GPS co-ordinates and the time, my map was always at night time in the game or editor. Thus, I was seeing this has a problem but actually these co-ordinates, actually dictates the time "in real life" sort to say.
I just boosted my time a little and, Voila! done deal.
So everything is well and done for. Except I need create my cities now one by one. Huh! That will be fun.
P.S.: I will get back to everyone in a year... Lol, Nah!
