Sometimes something happens that causes my characters to turn too fast. It seems like my "look sensitivity" setting somehow changed from current 3 to 300. It's especially notable when running - you can make a 90 degree turn instantly without any "inertia" that was there before. It's so fast that it's distracting and it makes me quit or load the game/session again. This has mostly happened to me on patrols, sometimes perhaps with strikes too. This does not have anything to do with perks/weapons affecting character movement speed, because it can happen without any of those equipped. I am not sure if this is related, but I just had it happen to me after I used a blade of Crota for awhile. Was patrolling the moon, the crota thing happened and I got the sword, then dropped it. After that my character can make steep turns instantly at full speed against laws of physics. I'm sure this didn't happen before the major multi-gigabyte patch. The platform is Xbox One. I have the DLC, but this happened before the release of TDB too. At least one of my friend has had this issue as well.
