That seems to be a general service problem.
The same can happen to Ambulances, Police, Fire Trucks, Garbage Trucks, and Recycling Trucks. You provide a service from your main city whilst you build a new city. Once the new one is up and running, providing it's own services, you cancel the regional help ...... but the help continues and never stops.
There is something to complain about - If they don't fix the (bug?) issue, where you cannot take over an abandoned city, if you don't own the dlc used to build it. It just fragments the player base.
Interesting, I posted a link to your website (in EA's Simcity - General Discussion thread) entitled "Latest Sim News ..... Spoof"
I made it clear that it is a spoof. It was gone within 5 minutes, not even a PM to me telling why.
The forum of is full of posts like "This game is crap" etc. Yet a mildly humorous dig gets their gander up ....
I don't think you can change the darkness into light in this game, which you could do in SC4
As for the edge scrolling .... yes it's annoying as I get it too. I would like either a smaller mouse pointer, or the control moved away from the edge a tiny bit. Or perhaps there should be a slight delay when touching the edge before the scroll starts. It really irritating when going for the control in the lower right corner, where you can bring up the overlay menu
