unless you can reproduce it with a step-by-step will be hard even to a plugin fix it.
I play vs everyday and never have seen this bug, besides the videos and reports

one of the best solutions given was to check if the player moved too far from the last second (with an incapped survivor) and is near from the 0,0,0 pos. No point in checking outside world cause in some maps 0,0,0 is inside the map.

Still has to consider ghost spawns and tank controls on this.
