Feral Heart

I was playing with a friend and was guiding my character using my mouse. then all of a sudden, it did not matter where the camera was facing I went forward in the direction my characters body was facing, not the camera. To change the way it was facing, I had to use the A and D keys and could not go sideways; i just spun in a circle. It was all my chaqracters that did this. My friend also had this happen. She says it goes away after a while but I would like this fixed right away. I think it just happens to more peolpe than just my friend. This new manoeuvring is really hard to use.  DX
