I believe they were dropped due to lack of traffic. The 173rd clanDoD 1.6 server is now ZombieMod #2, for example.
Nice wallhack by the way
I have had a couple glitches like that in CS:S where all of the Boxes on the map would be transparent. It is caused by the engine not rendering prop_detail objects in the map. Mine was caused by a video card glitch, your was likely something similar, looks like it wasnt rendering func_wall entities in the map.
Thanks for coming here and asking about it, most would just leave it as a wallhack!
