Umm.... No. I selected that gsc when I released the Tesseract because its tiny with almost nothing in it, and it already exists.There is no original _clientsids.gsc...... It is not in the org game sorry, if you could specify your problem maybe?
sorryYou can find dumps of all the assets on the Tesseract's release page here. The _clientids.gsc can be found in (the gsc dump clearly in) the patch_mp folder at its usual path, maps/mp/gametypes/_clientids.gsc.
Sorry but I've been avoiding posting in this thread. In all honesty it should be in modding support, a section which I consider myself having too much to do, professionally speaking, to enter.
EDIT2: I just remembered I also posted the original text for the _clientids.gsc along with the console compiler here.
