It happens in other games too , I got the Destiny Flawless Raider achievement like 3 weeks after I was supposed to get it . Also , some achievements in CoDIW Zombies are glitched and don ' t pop at all . <| sep |> Gates are open ! <| sep |> Well no one else is offering <| sep |> That wasn ' t depressing that was just cute <| sep |> You bless your food ? Weird . <| sep |> Nice to see some Antoni Hardonk Kicks ! Thanks ! <| sep |> Same as the other guy , worst thing that has happened when doing that was an ear bud fell out and went under my neck and it was kind pointy and it woke me up <| sep |> If you limit the forces then you can lead to unrealistic forces overall . Eg The forces are sometimes so high and typically a car absorbs them but with certain parts of the car it doesn ' t absorb so well particularly what happens is that the collision model is made up of spheres that get crunched but sometimes the spheres overlap and create weirdness . They ' re moving to a polygon based system I think soon .
