Fix back stab glitch for Spy in Team Fortress 2

As frequent players of Team Fortress 2 have noticed, there is a glitch involving the back stab for the Spy. It has been determined through various players whose preferred class is the Spy, that this glitch is not on the users end. This happens to players on anywhere from 24-32 man servers, and a ping ranging from 10-70 for both the Spy player and his intended target.

To make this clear, this petition is not a complaint about the stab animation; but about a back stab not registering and in many cases a face stab occurs. It is a recurring bug that happens at completely random times excluding the face stab which may be exploited by skilled players. The back stab glitch happens when the Spy player is directly behind his target, often times the target is not moving at all, as is the Spy player, when the Spy does a back stab, it fails to register, this can happen multiple times for the same target, the end result being that the Spy is killed for his effort.

Whereas a Spy player can master this exploit, which results in a face stab, much to the chagrin of every class in the game.

As loyal customers who have purchased Valve products since the days of Half Life, the lack of correspondence over this issue is distressing. As someone who paid fifty dollars for the Orange Box on PC largely for Team Fortress 2, I expect the product to be working, there are things server-related that can't be helped of course, but when a bug like this has gone on for many months now... one questions if they should buy future products by the same company if they continue to ignore a request by their customers to fix a bug that is on the companies end.
