Mindcraft and corrupting monsters
Killing corrupting monsters that stand behind other monsters with mindcraft crashes the game.
Take a situation like this: @gr (the r is a chaos rat). When you kill the chaos rat with mindcraft the game seemingly tries to corrupt you after the rat is dead. That possibly causes a small pointer problem because the rat simply doesn't exist anymore; and thus adom crashes.
