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.
I dont understand 'open the map's RFA file with cruachan's rfa-explorer, browse to the "Textures" directory, and simply replace the corrupted envmap_g.rcm file with the one from your extracted map.' It sounds like your saying to replace the envmap_g.rcm with the same corupted version of the file.
But good job for working it out i hope i can work this out will be huge help gj.
