Ya glitching in S:ca isn't a big thing to worry about. The vehicles aren't someone glitching this is just where zipper screwed up big time. Once cars are blown up everybody will see different crap. Some people might see a guy floating(even though hes in the driver seat), some might be able to drive it but can't run people over, and others might be able to see it but not be able to get in it. Hopeful a this gets patched asap. And "wall hax" unless people found new crap, doubt it, they got there by accident such as spawning there or something like that. Although you can still use weapons your not suppose to in rooms, such as air burst in Snipe no cross.
I must say zipper did an okay job on fixing glitches.
