Wow....thats something I havent seen before. A server-side wall hack? lol
If that was something YOU had happening to you only then it would be an issue. The video obviously shows all the other players experiencing the same thing so there is proof that it was a server issue.
Recording that was a very smart thing to do. Had that server been streaming screenshots to an anti-cheat org., you might have gotten a ban! The video would have proved your innocence.
Good times!
