Saturation, are you entirely sure the server has anti-cheat installed? If it
does then 2015 need to know about this.
I'd strongly suspect the anti-cheat isn't installed, though. Worth at least asking an admin of the site to make sure.
That's all I can really think of. I seriously doubt that 2015 would make a fix for a client side cheats bug and only fix the 'god' aspect of it, neglecting the 'no clip and 'all weapons' cheats.
I'd hope not, anyway
