Updated trainer has been sent and will be posted soon. I've also added options for increasing students, workers and shoppers.
I've taken a look on the ControlNET request but that requires an expansion pack we do not own. About the resources I've managed to edit them but not to add them to the trainer as it requires a different hook which seems to be highly unstable.
It appears to be the game has several values where changes (although they apply correctly) have no impact. In fact of the story / past of SimCity it doesn't surprise me at all. However I might take a look on more features on next game update.
