Last Month the Japanese try to retrive this mod a little bit more. They played in the at 2pm CET. At the moment the gametracker,com Server Monitorring is off. Hope soon they turn it on. The ranking seems to work.
The official line on BC textures is to go into your texturesets folder, make a copy of the default folder, and then edit the bitmaps.
However, everytime you restart BC, it forgets which texture set you have chosen to use, and so you can waste time making surface maps with the wrong textures.
So my advice is make a backup of your default folder, and then just edit the default folder itself, which saves you a lot of hassle.
