Well last night (right after the update) they had quite the list of errors. Ranging from semi-god mode to knives.
Anyhow...
Knives were unlocked for almost everyone, you had normal weapons on either your last class you used or the last class you equiped a weapons with.

Kinda pointless part because almost everyone got them, they didn't really do much. You could run faster with them and it damaged someone about 40%/bleeding to death when you hit. You could only hit a person once. after that it was null.
Semi Godmode was pretty nice in CS maps. What you had to do was find a place where you could fall and get damage from. You jump off and the you hear the blood sound. Health HAS to be taken away by the fall. But with the new update it didn't have any yellow message saying 'Whatever% damage from fall'. Now you have Semi God mode on, semi because vehicles are the only things that can hurt you now. I don't have pics for this one, and they are probably going to patch it in the next update.
Walking through walls was also a glitch they had. There were random parts of the maps you could walk into the sidewalks, etc. This was on the new maps and old. Another thing they will probably patch. No Screen shot right now. I'll get one once my computer stops lagging.
