today it happened for the second time. I have no idea how to reproduce. I was playing on UK 0-08 at around 17:30 and lost control of the character, and he continued to move. I was chased by a zombie.

After thirty seconds or so the putting away of the rifle had registered. My movement changed into a circular/random one. My view was all over the place, tumbling around, up and down. Impossible to act with purpose. The zombie continued to maul me to death.
