i play on ps3, and i am trying to do 2 story missions. when i choose either mission, i get two prompts: press "x" to resume, or press "square" to restart. the problem is no matter which one i press, it takes me to the exact same checkpoint. i noticed this because i quit a mission last week after killing the divisive mind. there is a bounty today to kill him again. i tried to reload my checkpoint, but the divisive mind does not respawn. so i tried to restart the mission, and hitting the square button and the "x" button both take me directly to the checkpoint. is this a bug in the game? does anyone else have this problem with not being able to restart a mission?
