When this unusual occurrence occurs, it usually happens to at least 2 or 5 players on the server (sometimes it even happens to half, if not all).

An immense amount of server lag is the culprit. It doesn’t happen often, but when it does…. Oh baby.. you will either drop everything you own, be shot in the back (FF on), die horribly, die with great embarrassment, or just plain die because you have dropped your nade and BOOM! Your ass lands next to your face! eatthis:

Live with it my friend.

Or get a better connection and change servers.
