This bug works every single time on any of the game modes mentioned above, as well as others I am sure.
The exploit involves some sort of buffer overflow.
Use of the exploit will cause the player's game to crash and will instantly crash the server it is used on.
Worse, players will often fail to get the "no message received" and will continue playing until they come across another player stuck running in place and realize that side chat has stopped, and they cannot interact with in game objects such as vehicles or loot.
This exploit does not work on epoch mod because epoch mod has removed the "grab" prompt.
This exploit was used on my exile server two days ago and yesterday it was used on pretty much every single major exile server.
