Invisible Barriers have been heavily improved to be much more tidy and to create a nice safe environment for the players.
Grunts should not be able to get in and players should not be able to get out.

Almost all Grunts have been gone over and rescripted to ensure they are unable to get angry enough to the point where they are able to defy physics and break through invisible barriers.
All fights and extreme violence have also been slightly lowered to a safer level.
