first of all, very nice patch
as some of you may have already figured out, there's a way to avoid the chain net in the urban court being replaced. That's doing it the "hard way", using the EA Graphic Editor to import the tnet.fsh to every .viv file in sgsm\stadia, except urba.viv.
I'm sure not many of you(including myself) actually like the chain net in the urban court, but just a little piece of info for those who likes it.
EDIT: Oh yea, if you are choosing the hard way, there is no need for you to place the tnet.fsh in sgsm folder anymore
